48. Case Study:Insertion Sort • Pick the first card: it forms the trivially sorted list {a1}. • Pick the next card from the table, and insert it into the correct place (i.e., before or after a1), giving the sorted list {a1, a2}. • Pick a third cards and insert it into the correct place in the list. Now we have sorted {a1, a2, a3}. • In general, at step j , insert aj into the correct location of {a1, a2, … ,aj-1}.

49. 1 j n 1 3 14 17 28 6 … algorithm Insertion (A[1..n]) • initialize: sort A[1] • for j = 2 to n • key = A[j] • i = j -1 • while i > 0 and A[i] > key • A[i+1] = A[i] • i ← i -1 • A[i +1] = key At the end of each pass j through the algorithm given above, the entries in the sublist {a1; a2; … ; aj } are first j entries of the original list, but in sorted order.

50. One step of insertion sort • The outer loop (j) will be executed (n-1) times. • Each time j is incremented (i.e each pass): • list A[1, …, j-1] is already sorted. • A[j] is inserted to the part of the list A[1, …, j-1]. • The insertion requires [ 1 to j-1] steps. • In the worst case, the insertion takes [j-1] steps. • The inner loop is executed • Note: In the best case: The insertion requires 1 step. So, inner loop is executed :
