Then, it merges adjacent subarrays in a sorted manner until the entire array is sorted. The merging process compares elements from each subarray and places them in the correct order.

Insertion sort works by iteratively selecting an element from the unsorted portion of the array and inserting it into its correct position in the sorted portion of the array. The algorithm maintains two subarrays: the sorted subarray and the unsorted subarray. Initially, the sorted subarray is empty, and the unsorted subarray contains all elements of the input array. In each iteration, insertion sort takes the first element from the unsorted subarray and inserts it into its correct position in the sorted subarray, shifting elements if necessary.
