 **push_swap** is a project from 42 School that challenges you to sort data using a limited set of operations. In this project, you will implement an efficient algorithm that sorts a stack of integers using two stacks (A and B) and a predefined set of instructions. The main objective is to minimize the number of operations needed to achieve a sorted stack.
