Information:

Insertion sort is a simple sorting algorithm that builds the final sorted array one item at a time. It is much less efficient on large lists than more advanced algorithms such as quicksort, heapsort, or merge sort. In insertion sort, each iteration removes an element from the input data, finds the location it belongs within the sorted list, and inserts it there.

Complexity:

The space complexity is O(1), the best case time complexity is O(N) and the average/worst case time complexity is O(N^2).
