Random Walk Simulation

The function simulates a random walk process. Given the number of steps and the starting point, the function returns the coordinates of each step.

Technology Stack : The function uses the following packages and technologies: Python standard library (random module)

Code Type : The type of code

Code Difficulty : Advanced
