The array is virtually split into a sorted and an unsorted part. Insertion sort is a very simple method to sort numbers in an ascending or descending order. It always maintains a sorted sublist in the lower positions of the list. Question 4: When is it best to use Selection Sort? Answer: Selection Sort is best used for small datasets, educational purposes, or when memory usage needs to be minimal. Each new item is then “inserted” back into the previous sublist such that the sorted sublist is one item larger. . Initially, the first element is already considered sorted, while the rest of the list is considered unsorted. Here is an implementation.
