Insertion Sort
Insertion sort is a simple sorting algorithm that works by iteratively building a sorted sub-array from left to right. The idea behind insertion sort is to take one element at a time and insert it into its correct position in the already sorted sub-array to its left.
Here's how insertion sort works:
- We start with the first element of the array as our initially sorted sub-array.
- For each element in the unsorted part of the array, we compare it to the elements in the sorted sub-array from right to left until we find the correct position for the element.
- Once we have found the correct position, we insert the element into the sorted sub-array at that position.
- We repeat this process until all elements in the unsorted part of the array have been inserted into the sorted sub-array.
This process is repeated until the entire array is sorted. Insertion sort has a worst-case time complexity of O(n^2), but in practice, it is often faster than other algorithms for small arrays or nearly sorted arrays.
