Here is the description of a new assembly language: * 8 registers (R1, R2, R3, R4, R5, R6, R7, R8) that can hold integers. * 1 flag that can hold a boolean value (True or False). * 100 memory addresses (0-99) that can hold integers. * 1 instruction pointer that points to the current instruction being executed. Each instruction is of the form OP ARG1 ARG2 ... where ARGn can be either a register (e.g., R1) or a constant (e.g., 10). Labels are written with a lowercase word followed by colon. The assembly language supports the following instructions: * SET Rx C: Assigns the value C to register Rx. * ADD Rx Ry Rz: Adds the values of Ry and Rz and stores the result in Rx. * (similarly for SUB, MUL, DIV, MOD) * EQ Rx Ry: Sets the flag to True if Rx and Ry are equal, False otherwise. * (similarly for NEQ, LT (Rx < Ry), LTE, GT, GTE) * INC/DEC Rx: Increments/Decrements the value of Rx by one. * JMP L: Jumps to label L unconditionally. * JT/JF (jump if true / jump if false) L: Jumps to label L if the is set or not set. * LOAD Rx M: Loads the value at memory address M into register Rx. * STORE Rx M: Stores the value of register Rx into memory address M. * HCF: Stops the program (with pizzazz) For example here is a program to compute the first 20 square numbers (1, 4, 9, 16, 25, ...): SET R1 0 // Counter for storing squares SET R2 1 // Number to square loop: MUL R3 R2 R2 // R3 = R2 * R2 STORE R3 R1 // Store R3 at address R1 INC R1 // Increment address INC R2 // Increment number SET R3 20 EQ R1 R3 // Check if 20 squares are found JF loop // If not 20 squares found yet, continue finding end: HCF // Stop program Write me a python interpreter `evaluate(str)` that returns the resulting memory state after running the program. For example, `evaluate(program)` should return `[1, 4, 9, 16, 25, ...]` for the above program.

print(evaluate(program))
This implementation does the following: 1. Preprocesses the program to handle labels and remove comments 2. Implements all the specified instructions 3. Tracks registers, memory, flag, and instruction pointer 4. Allows both register and constant arguments 5. Supports jumping based on labels and flag state 6. Stops on HCF instruction When you run this with the squares program, it will output:
1
[1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, 169, 196, 225, 256, 289, 324, 361, 400]
The function `evaluate(program)` takes the assembly language program as a string and returns the first 20 memory locations after the program runs. You can test it with different programs by passing in the assembly code as a multi-line string.

Here is the description of a new assembly language: * 8 registers (R1, R2, R3, R4, R5, R6, R7, R8) that can hold integers. * 1 flag that can hold a boolean value (True or False). * 100 memory addresses (0-99) that can hold integers. * 1 instruction pointer that points to the current instruction being executed. Each instruction is of the form OP ARG1 ARG2 ... where ARGn can be either a register (e.g., R1) or a constant (e.g., 10). Labels are written with a lowercase word followed by colon. The assembly language supports the following instructions: * SET Rx C: Assigns the value C to register Rx. * ADD Rx Ry Rz: Adds the values of Ry and Rz and stores the result in Rx. * (similarly for SUB, MUL, DIV, MOD) * EQ Rx Ry: Sets the flag to True if Rx and Ry are equal, False otherwise. * (similarly for NEQ, LT (Rx < Ry), LTE, GT, GTE) * INC/DEC Rx: Increments/Decrements the value of Rx by one. * JMP L: Jumps to label L unconditionally. * JT/JF (jump if true / jump if false) L: Jumps to label L if the is set or not set. * LOAD Rx M: Loads the value at memory address M into register Rx. * STORE Rx M: Stores the value of register Rx into memory address M. * HCF: Stops the program (with pizzazz) For example here is a program to compute the first 20 square numbers (1, 4, 9, 16, 25, ...): SET R1 0 // Counter for storing squares SET R2 1 // Number to square loop: MUL R3 R2 R2 // R3 = R2 * R2 STORE R3 R1 // Store R3 at address R1 INC R1 // Increment address INC R2 // Increment number SET R3 20 EQ R1 R3 // Check if 20 squares are found JF loop // If not 20 squares found yet, continue finding end: HCF // Stop program Write me a python interpreter `evaluate(str)` that returns the resulting memory state after running the program.

This implementation follows the assembly language specification you provided. Key features: 1. Handles all specified instructions 2. Supports labels and jumps 3. Manages 8 registers, 100 memory addresses, and a flag 4. Preprocesses the code to map labels to instruction indices 5. Resolves arguments as either register values or constants 6. Supports comments (anything after //) When you run this with the square numbers program, it will output the first 20 square numbers: `[1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, 169, 196, 225, 256, 289, 324, 361, 400]` You can test it with other assembly programs following the same syntax and instruction set.

Initial Query

Here is the description of a new assembly language: * 8 registers (R1, R2, R3, R4, R5, R6, R7, R8) that can hold integers. * 1 flag that can hold a boolean value (True or False). * 100 memory addresses (0-99) that can hold integers. * 1 instruction pointer that points to the current instruction being executed. Each instruction is of the form OP ARG1 ARG2 ... where ARGn can be either a register (e.g., R1) or a constant (e.g., 10). Labels are written with a lowercase word followed by colon. The assembly language supports the following instructions: * SET Rx C: Assigns the value C to register Rx. * ADD Rx Ry Rz: Adds the values of Ry and Rz and stores the result in Rx. * (similarly for SUB, MUL, DIV, MOD) * EQ Rx Ry: Sets the flag to True if Rx and Ry are equal, False otherwise. * (similarly for NEQ, LT (Rx < Ry), LTE, GT, GTE) * INC/DEC Rx: Increments/Decrements the value of Rx by one. * JMP L: Jumps to label L unconditionally. * JT/JF (jump if true / jump if false) L: Jumps to label L if the is set or not set. * LOAD Rx M: Loads the value at memory address M into register Rx. * STORE Rx M: Stores the value of register Rx into memory address M. * HCF: Stops the program (with pizzazz) For example here is a program to compute the first 20 square numbers (1, 4, 9, 16, 25, ...): SET R1 0 // Counter for storing squares SET R2 1 // Number to square loop: MUL R3 R2 R2 // R3 = R2 * R2 STORE R3 R1 // Store R3 at address R1 INC R1 // Increment address INC R2 // Increment number SET R3 20 EQ R1 R3 // Check if 20 squares are found JF loop // If not 20 squares found yet, continue finding end: HCF // Stop program Write me a python interpreter `evaluate(str)` that returns the resulting memory state after running the program.

This implementation does the following: 1. Parses the program, removing comments and whitespace. 2. Creates a mapping of labels to line numbers for jumps. 3. Initializes registers, memory, flag, and instruction pointer. 4. Implements each instruction type with its corresponding logic. 5. Supports getting values from either registers or constants. 6. Uses labels for jumps. 7. Stops when HCF instruction is encountered. When you run this with the square numbers program, it will return the first 20 square numbers stored in memory: `[1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, 169, 196, 225, 256, 289, 324, 361, 400]` You can test it with different programs by passing the program string to `evaluate()`.

Initial Query

Here is the description of a new assembly language: * 8 registers (R1, R2, R3, R4, R5, R6, R7, R8) that can hold integers. * 1 flag that can hold a boolean value (True or False). * 100 memory addresses (0-99) that can hold integers. * 1 instruction pointer that points to the current instruction being executed. Each instruction is of the form OP ARG1 ARG2 ... where ARGn can be either a register (e.g., R1) or a constant (e.g., 10). Labels are written with a lowercase word followed by colon. The assembly language supports the following instructions: * SET Rx C: Assigns the value C to register Rx. * ADD Rx Ry Rz: Adds the values of Ry and Rz and stores the result in Rx. * (similarly for SUB, MUL, DIV, MOD) * EQ Rx Ry: Sets the flag to True if Rx and Ry are equal, False otherwise. * (similarly for NEQ, LT (Rx < Ry), LTE, GT, GTE) * INC/DEC Rx: Increments/Decrements the value of Rx by one. * JMP L: Jumps to label L unconditionally. * JT/JF (jump if true / jump if false) L: Jumps to label L if the is set or not set. * LOAD Rx M: Loads the value at memory address M into register Rx. * STORE Rx M: Stores the value of register Rx into memory address M. * HCF: Stops the program (with pizzazz) For example here is a program to compute the first 20 square numbers (1, 4, 9, 16, 25, ...): SET R1 0 // Counter for storing squares SET R2 1 // Number to square loop: MUL R3 R2 R2 // R3 = R2 * R2 STORE R3 R1 // Store R3 at address R1 INC R1 // Increment address INC R2 // Increment number SET R3 20 EQ R1 R3 // Check if 20 squares are found JF loop // If not 20 squares found yet, continue finding end: HCF // Stop program Write me a python interpreter `evaluate(str)` that returns the resulting memory state after running the program. For example, `evaluate(program)` should return `[1, 4, 9, 16, 25, ...]` for the above program.

Here is the description of a new assembly language: * 8 registers (R1, R2, R3, R4, R5, R6, R7, R8) that can hold integers. * 1 flag that can hold a boolean value (True or False). * 100 memory addresses (0-99) that can hold integers. * 1 instruction pointer that points to the current instruction being executed. Each instruction is of the form OP ARG1 ARG2 ... where ARGn can be either a register (e.g., R1) or a constant (e.g., 10). Labels are written with a lowercase word followed by colon.

This implementation does the following: 1. Preprocess the program to create a label map for efficient jumping. 2. Initialize registers, memory, and flag. 3. Implement each instruction type with the specified behavior. 4. Use an instruction pointer to track program execution. 5. Handle jumping based on labels and flag conditions. When you run this with the square numbers program, it will return the first 20 square numbers in memory: `[1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, 169, 196, 225, 256, 289, 324, 361, 400]` You can modify the program or test different assembly language programs with this interpreter.

Here is the description of a new assembly language: * 8 registers (R1, R2, R3, R4, R5, R6, R7, R8) that can hold integers. * 1 flag that can hold a boolean value (True or False). * 100 memory addresses (0-99) that can hold integers. * 1 instruction pointer that points to the current instruction being executed. Each instruction is of the form OP ARG1 ARG2 ... where ARGn can be either a register (e.g., R1) or a constant (e.g., 10). Labels are written with a lowercase word followed by colon. The assembly language supports the following instructions: * SET Rx C: Assigns the value C to register Rx. * ADD Rx Ry Rz: Adds the values of Ry and Rz and stores the result in Rx. * (similarly for SUB, MUL, DIV, MOD) * EQ Rx Ry: Sets the flag to True if Rx and Ry are equal, False otherwise. * (similarly for NEQ, LT (Rx < Ry), LTE, GT, GTE) * INC/DEC Rx: Increments/Decrements the value of Rx by one. * JMP L: Jumps to label L unconditionally. * JT/JF (jump if true / jump if false) L: Jumps to label L if the is set or not set. * LOAD Rx M: Loads the value at memory address M into register Rx. * STORE Rx M: Stores the value of register Rx into memory address M. * HCF: Stops the program (with pizzazz) For example here is a program to compute the first 20 square numbers (1, 4, 9, 16, 25, ...): SET R1 0 // Counter for storing squares SET R2 1 // Number to square loop: MUL R3 R2 R2 // R3 = R2 * R2 STORE R3 R1 // Store R3 at address R1 INC R1 // Increment address INC R2 // Increment number SET R3 20 EQ R1 R3 // Check if 20 squares are found JF loop // If not 20 squares found yet, continue finding end: HCF // Stop program Write me a python interpreter `evaluate(str)` that returns the resulting memory state after running the program.

Key features of this implementation: 1. Handles all specified instructions 2. Supports labels and jumping 3. Preprocesses the program to map labels to line numbers 4. Uses helper function `get_value()` to handle both register and constant values 5. Modifies memory in-place as the program runs 6. Stops when HCF instruction is encountered 7. Ignores comments (anything after `//`) When you run the example program, it will output the first 20 square numbers: `[1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, 169, 196, 225, 256, 289, 324, 361, 400]` You can modify the interpreter or test different programs using the `evaluate()` function.
