Derive time complexity for insertion sort

WebApr 10, 2024 · Insertion sort is a simple sorting algorithm that works similar to the way you sort playing cards in your hands. The array is virtually split into a sorted and an unsorted part. Values from the unsorted part are … WebNov 5, 2016 · There are two factors that decide the running time of the insertion sort algorithm: the number of comparisons, and the number of movements. In the case of number of comparisons, the sorted part (left side of j) of the array is searched linearly for the right place of the j t h element.
