Insertion sort is a classical sorting algorithm, in which each element is compared with its previous elements. for example {1,3,5,34,6}. 3 is compared with 1 ,since 3 is greater than 1 no interchange is required.again 5 is compared with its previous element 1 and 3. as 5 is greater than both 1 and 3 nothing would happen. now 34 is compared with 1,3,5 and since all the elements are less than 34 ,nothing would happen.Again 6 is compared with 1,3,5,34. as 6 is less than 34, at the place of 34, 6 will be placed.

Insertion sort is an “in place” algorithm, no memory allocations are required.
