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.

This interpreter: 1. Initializes the machine state (registers, memory, flag) 2. Parses the program into lines and removes comments 3. Extracts labels and their corresponding line numbers 4. Executes instructions one by one, updating the machine state accordingly 5. Returns the non-zero part of memory when the program halts The interpreter handles all the specified instructions and supports: - Arithmetic operations (ADD, SUB, MUL, DIV, MOD) - Comparison operations (EQ, NEQ, LT, LTE, GT, GTE) - Control flow (JMP, JT, JF) - Memory operations (LOAD, STORE) - Register operations (SET, INC, DEC) For the example program, it correctly computes and stores the first 20 square numbers in memory.

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 interpreter: 1. Initializes the machine state (registers, memory, flag) 2. Parses the program, removing comments and handling labels 3. Implements a helper function to get values from either registers or constants 4. Implements all the specified instructions 5. Executes the program one instruction at a time until HCF is reached 6. Returns the non-zero part of memory For the example program computing squares, it correctly returns the first 20 square numbers. The interpreter handles all the specified instructions and follows the described behavior. It also: - Ignores comments (anything after //) - Handles labels correctly - Processes both register and constant arguments - Implements all arithmetic, comparison, and control flow operations - Manages memory operations properly You can test it with other programs by simply passing them as strings to the `evaluate()` function.

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 interpreter: 1. Initializes the machine state (registers, memory, flag) 2. Parses the program, removing comments and empty lines 3. Extracts labels and their corresponding instruction positions 4. Executes instructions one by one until HCF is reached 5. Returns the non-zero portion of memory The interpreter handles all the specified instructions and properly manages: - Arithmetic operations (ADD, SUB, MUL, DIV, MOD) - Comparison operations (EQ, NEQ, LT, LTE, GT, GTE) - Control flow (JMP, JT, JF) - Memory operations (LOAD, STORE) - Register operations (SET, INC, DEC) For the example program computing square numbers, it correctly returns the first 20 square numbers stored in memory.

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 interpreter: 1. Initializes the machine state (registers, memory, flag) 2. Parses the program, removing comments and empty lines 3. Extracts labels and their corresponding instruction indices 4. Executes instructions one by one until HCF is encountered 5. Returns the non-zero part of memory You can test it with your square numbers program:

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.

This interpreter: 1. Initializes the machine state (registers, memory, flag) 2. Parses the program, removing comments and handling labels 3. Executes instructions one by one, updating the machine state accordingly 4. Returns the non-zero portion of memory when the program terminates The interpreter handles all the specified instructions and properly manages the program flow with labels and jumps. It also includes error handling for division by zero and invalid memory addresses. For the example program calculating square numbers, it correctly produces an array of the first 20 square numbers. You can test it with different programs by simply passing them as strings to the `evaluate()` function.
