WebJan 11, 2024 · Insertion sort: Insertion sort is a basic sorting algorithm that operates in the same manner that you arrange cards in your hands. The array is divided into two halves, one sorted and one not. Values from the unsorted section are selected and placed in the sorted section at the appropriate location. Explanation: Consider the array is, WebJul 3, 2024 · Here we see the first few iterations of Insertion Sort. Insertion Sort starts with the record in position 1. This continues on with each record in turn. Call the current record x . Insertion Sort will move it to the left so long as its value is less than that of the record immediately preceding it.
