To solve this problem, you can use the following Python script (don’t forget to change image_name and max_minutes to your environment):

Whenever our program has loaded, all functions and methods are placed at specific memory addresses of the virtual address space assigned to the process of our running program. Whenever a function calls another function, it doesn’t call the name of the function but the address where the function is located in memory.
