Detailed Description

Implements the OP_APOP opcode for removing elements from arrays in the VM.

This file handles the OP_APOP instruction, which removes the last element from an array and pushes the removed element onto the stack. The array is popped from the stack.

Behavior:

• Pops the array from the stack.
• Removes the last element from the array.
• Pushes the removed element onto the stack.

Error Handling:

• Exits with an error if the array is of the wrong type.
• Exits with an error if the array is empty.

Example: // Bytecode: OP_APOP // Stack before: [[10, 20, 30]] // Stack after: [30]
