Output

Based on the provided Python bytecode disassembly, it's clear this code is performing a series of mathematical and array manipulations, likely related to matrix operations given the use of attributes like `shape` and methods from the `numpy` library (`np`). This function, which we'll name `foo`, appears to perform operations on a given matrix to presumably put it in a reduced row echelon form or perform some similar transformation, considering the variable naming and operations performed. Let's reconstruct a Python function that captures the essence of these operations. Note that due to the nature of bytecode, some assumptions about variable names and the broader context (like the content of the list comprehensions) have to be made. The given bytecode snippet suggests a focus on matrix manipulation, so we'll assume `matrix` is a numpy array, and operations like modulo (`%`), shape inspection, and element-wise operations are used accordingly.

import numpy as np

def foo(matrix, PH, graphlen):
    extra = 0
    col = 0
    pivots = []
    used_for_row = [set(range(matrix.shape[0])) for _ in range(matrix.shape[0])]

    matrix = matrix % PH

    while col + extra < matrix.shape[1] - 1 and col < matrix.shape[0]:
        if matrix[col + extra, col] == 0:
            if np.all(matrix[:, col] == 0):
                extra += 1
                continue
            
            other = np.argwhere(matrix[:, col + extra] != 0).flatten()[-1]

            if other < col:
                extra += 1
                continue
            
            # Swap rows in matrix and in used_for_row
            matrix[[col, other], :] = matrix[[other, col], :]
            used_for_row[col], used_for_row[other] = used_for_row[other], used_for_row[col]
        
        pivots.append(col + extra)
        pivot = matrix[col, col + extra]

        # Pivot adjustments
        if col + extra < graphlen:
            assert np.abs(pivot) in {1, PH - 1}, "Invalid pivot value"
        else:
            assert np.abs(pivot) in {2, PH - 2}, "Invalid pivot value"
            pivot //= 2
        
        matrix[col, :] *= pivot
        matrix[col, :] %= PH

        # Row reduction
        others = np.argwhere(matrix[:, col + extra] != 0).flatten()
        for i in others:
            if i == col:

            if col < graphlen:
                matrix[i, :] -= matrix[col, :] * matrix[i, col + extra]
            elif matrix[i, col + extra] != 0:
                matrix[i, :] -= matrix[col, :]
                matrix[i, :] %= PH
            matrix[i, :] %= PH
        
        col += 1

    matrix = np.array(matrix) % PH

    # The final transformations based on used_for_row are not detailed, so we return the modified matrix and pivots
    return matrix, pivots, [sorted(x) for x in used_for_row]

This reconstructed function, `foo`, takes a `matrix`, a modulus `PH`, and a `graphlen` parameter. It performs a sequence of operations that might be part of a broader algorithm for matrix manipulation in a numerical or algorithmic context. The reconstructed function includes assumptions about the purpose of the operations and the intended logic that matches the described bytecode, especially regarding the handling of pivot elements and row operations.

Based on the disassembled bytecode you've provided, it appears to be a part of a Python program that performs some operations on a matrix, possibly related to row reduction or similar linear algebraic manipulations. The program involves numpy for matrix operations, and it's adjusting the matrix based on certain conditions and calculations. Given the complexity and the specific details provided in the bytecode, I'll sketch out a Python function `foo` that captures the main operations as described by the bytecode. However, please note that without the actual context and purpose of the original Python code, some assumptions have to be made regarding the function's parameters and operations, especially regarding the list comprehensions and their intended purpose.

import numpy as np

    extra = 0
    col = 0
    pivots = []
    used_for_row = [set(range(matrix.shape[0])) for _ in range(matrix.shape[0])]

    matrix = matrix % PH

    while (col + extra < matrix.shape[1] - 1) and (col < matrix.shape[0]):
        if matrix[:, col + extra][0] == 0:
            if np.all(matrix[:, col] == 0):
                extra += 1
                continue
            other = np.argwhere(matrix[:, col + extra] != 0).flatten()[-1]
            if other < col:

This function attempts to replicate the operations described in the bytecode, with some educated guesses about the list comprehensions and overall structure of the function. Key operations include modulo adjustments of the matrix with `PH`, row swaps, condition checks on matrix elements, and adjustments based on the `graphlen` parameter. Please adjust the function as necessary to fit the precise requirements and context of your original Python code, as the disassembly only provides a limited view of the program's logic and intent.

Output

Based on the disassembled Python byte code you provided, it's evident that the code involves matrix manipulation, possibly for a row reduction or similar linear algebra operation. To convert this byte code back into Python code within a function `foo`, we have to make some assumptions about the functionality and variables used: 1. `matrix` seems to be a two-dimensional array or similar structure, likely a NumPy array given the usage of attributes like `shape` and methods from the NumPy library (`np`). 2. Operations such as modulo (`BINARY_MODULO`), addition (`BINARY_ADD`), and comparisons (`COMPARE_OP`) hint at manipulation of matrix elements and indices. 3. The use of `shape` attribute and slicing suggests that operations are performed on rows and columns of the matrix. 4. There are list comprehensions at the end, indicating the creation of new lists based on the existing matrix or other structures. Given these observations, let's try to craft a Python function that captures the essence of the provided byte code. Note that without the full context, some assumptions about the purpose and intermediate variables (like `graphlen`, `PH`, etc.) must be made.

import numpy as np

def foo(matrix, PH, graphlen):
    extra = 0
    col = 0
    pivots = []
    used_for_row = [set(range(matrix.shape[0])) for _ in range(matrix.shape[1])]
    
    matrix = matrix % PH
    
    while (col + extra) < matrix.shape[1] - 1 and col < matrix.shape[0]:
        if matrix[col, col + extra] == 0:
            if np.all(matrix[:, col] == 0):
                extra += 1
                continue
            other = np.argwhere(matrix[:, col + extra] != 0).flatten()[-1]
            if other < col:
                extra += 1
                continue
            
            matrix[col], matrix[other] = list(matrix[other]), list(matrix[col])
            used_for_row[col], used_for_row[other] = used_for_row[other], used_for_row[col]
        
        pivots.append(col + extra)
        pivot = matrix[col, col + extra]
        
        if col + extra < graphlen:
            assert np.abs(pivot) in {1, PH - 1}, "Pivot check failed"
        else:
            assert np.abs(pivot) in {2, PH - 2}, "Pivot check failed"
            pivot //= 2
        
        matrix[col] *= pivot
        matrix[col] %= PH
        
        for i in np.argwhere(matrix[:, col + extra] != 0).flatten():
            if i == col:
                continue
            used_for_row[i] |= used_for_row[col]
            if col < graphlen:
                matrix[i] -= matrix[col] * matrix[i, col + extra]
            else:
                if matrix[i, col + extra] != 0:
                    matrix[i] = (matrix[i] - matrix[col]) % PH
            matrix[i] %= PH
        
        col += 1
    
    matrix = np.array(matrix) % PH
    final_structure = [sorted(x) for x in used_for_row]
    return final_structure

This function is an attempt to translate the byte code operations back into Python code, focusing on matrix manipulations that resemble operations from linear algebra, particularly row reduction or echelon form transformation. The variables and operations have been inferred to best match the given byte code, with some liberties taken to fill in gaps where the byte code's original context was not fully clear.

Output

Based on the disassembled Python bytecode you've provided, we can reconstruct the original Python function. Given the complexity and detail within the bytecode, the reconstruction will attempt to follow the logic and operations indicated, focusing on the key operations performed on the matrix and other variables. Please note that due to the nature of bytecode, some assumptions about variable names (beyond those provided) and operations must be made. The reconstructed function attempts to capture the essence of operations such as matrix manipulation, loop iterations, and conditional checks. Here's the reconstructed Python function named `foo`:

import numpy as np

def foo(matrix, graphlen, PH):
    extra = 0
    col = 0
    pivots = []
    used_for_row = [{i} for i in range(matrix.shape[0])]  # Assuming matrix has an attribute shape

    matrix = matrix % PH

    while col + extra < matrix.shape[1] - 1 and col < matrix.shape[0]:
        if matrix[col, col + extra] == 0:
            if np.all(matrix[:, col] == 0):
                extra += 1
                continue
            other = np.argwhere(matrix[:, col + extra] != 0).flatten()[-1]
            if other < col:
                extra += 1
                continue
            matrix[[col, other]] = matrix[[other, col]]
            used_for_row[col], used_for_row[other] = used_for_row[other], used_for_row[col]
        pivots.append(col + extra)
        pivot = matrix[col, col + extra]
        if col + extra < graphlen:
            if not (np.abs(pivot) == 1 or np.abs(pivot) == PH - 1):
                assert False
        else:
            if not (np.abs(pivot) == 2 or np.abs(pivot) == PH - 2):
                assert False
            pivot //= 2
        
        matrix[col, col] *= pivot
        matrix[col, col] %= PH

        others = np.argwhere(matrix[:, col + extra]).flatten()
        
        for i in others:
            if i == col:
                continue
            used_for_row[i] |= used_for_row[col]
            if col < graphlen:
                matrix[i] -= matrix[col] * matrix[i, col + extra]
            else:
                if matrix[i, col + extra] != 0:
                    matrix[i] -= matrix[col]
                    matrix[i] %= PH
            matrix[i] %= PH
        col += 1

    matrix = np.array(matrix) % PH
    return [sorted(x) for x in used_for_row]

Given the bytecode, here are some key points about the reconstruction: 1. **Matrix Operations**: The original function performs various operations on a matrix, including element-wise modification, row swapping, and modulo operations with a given value `PH`. 2. **Looping and Conditionals**: The code iterates through columns and performs checks on matrix elements to decide on swapping rows or adjusting values. 3. **List Comprehensions**: Two code objects are list comprehensions that generate sets and sorted lists from iterables, which are reconstructed based on the bytecode for list comprehensions. This reconstruction aims to replicate the functionality as closely as possible based on the given bytecode. However, without the original Python source code, some specific details (especially variable names and the exact nature of some operations) are assumed based on standard practices and the operations presented.

Output

The provided Python bytecode represents a complex algorithm, potentially related to matrix operations, given the references to matrix shapes, modifications, and conditions related to matrix elements. To reconstruct a Python function named `foo` from this disassembly, we'll need to infer the purpose and logic behind these operations. Let's make some general assumptions based on the bytecode and typical conventions in matrix manipulation algorithms: 1. The function seems to be modifying a matrix (`matrix`) in-place, given the repeated loads and stores to this variable. 2. It uses some external variables like `np` (typically NumPy) for matrix operations. 3. The algorithm involves iterating over rows and columns, swapping elements, and performing arithmetic operations, which are common in matrix transformation algorithms (e.g., for reducing matrices to row-echelon form). 4. The constants and variables like `PH`, `extra`, `col`, `pivots`, `used_for_row`, and `graphlen` are used as part of the algorithm's logic. 5. The `<listcomp>` code objects indicate list comprehensions used within the function, likely for generating lists based on certain conditions. Given these observations, let's attempt to write a Python function encapsulating this logic. Note that due to the nature of bytecode, some assumptions about variable names and their roles within the algorithm are made, and specific details might not exactly match the original Python code but should capture the overall logic.

import numpy as np

def foo(matrix, PH, graphlen):
    extra = 0
    col = 0
    pivots = []
    used_for_row = [set(range(x)) for x in matrix.shape[0]]
    
    matrix %= PH
    
    while col + extra < matrix.shape[1] - 1 and col < matrix.shape[0]:
        if matrix[col, col + extra] == 0:
            if np.all(matrix[:, col] == 0):
                extra += 1
                continue
            other = np.argwhere(matrix[:, col + extra] != 0).flatten()[-1]
            if other < col:
                extra += 1
                continue
            matrix[col], matrix[other] = list(matrix[other]), list(matrix[col])
            used_for_row[col], used_for_row[other] = used_for_row[other], used_for_row[col]
        
        pivots.append(col + extra)
        pivot = matrix[col, col + extra]
        
        if col + extra < graphlen:
            if np.abs(pivot) == 1 or np.abs(pivot) == PH - 1:
                pass  # Conditions for pivot validity
            elif np.abs(pivot) == 2 or np.abs(pivot) == PH - 2:
                pivot //= 2
            else:
                assert False, "Invalid pivot value"
        
        matrix[col, col] *= pivot
        matrix[col] %= PH
        
        others = np.argwhere(matrix[:, col + extra]).flatten()
        for i in others:
            if i == col:
                continue
            used_for_row[i] |= used_for_row[col]
            if col < graphlen:
                matrix[i] -= matrix[col] * matrix[i, col + extra]
            else:
                if matrix[i, col + extra] != 0:
                    matrix[i] = (matrix[i] - matrix[col]) % PH
            matrix[i] %= PH
        
        col += 1
    
    matrix = np.array(matrix) % PH
    sorted_used_for_row = [sorted(x) for x in used_for_row]
    
    return matrix, sorted_used_for_row

This function attempts to encapsulate the operations described in the bytecode. However, without more context about the specific algorithm (e.g., whether it's related to Gaussian elimination, finding a reduced row echelon form, or another matrix operation), certain details like condition checks and list comprehensions' purposes are assumed based on common tasks in matrix manipulation.
