  2. Insertion Sort • Consists of N-1 passes • For pass P = 1 through N-1, insertion sort ensures that the elements in positions 0 through P are in the sorted order • In pass P, the element in the position P is moved left until its correct place is found among the first P + 1 elements. • Complexity - O(n2) www.gowrikumar.com
