What is in place algorithm?

An in-place algorithm is a method for solving a problem that transforms the input data directly, using a small, constant amount of additional space. This means it modifies the data structure (like an array or list) without requiring significant extra memory allocation. In-place algorithms are often used in sorting (e.g., QuickSort, Bubble Sort) to achieve efficiency in both time and space. The primary advantage is that they can be more memory-efficient, which is particularly valuable in environments with limited resources.
