= C
a[j] = Q
since < a[j] , break from inner loop
Number of comparisons in 1st Iteration = 1
After 1st Iteration:

3rd Iteration:

j = 3
a[j-1] = S
a[j] = A
since a[j-1] > a[j], exchange a[2] with a[3]
Array : C,Q,A,S,X,B,T

a[j] = A
since a[j-1] > a[j], exchange a[0] with a[1]

4th Iteration:
i = 4
j = 4
a[j-1] = S
a[j] = X
since a[j-1] < a[j], break from inner loop
Number of comparisons in 4th Iteration = 1
After 4th Iteration:

5th Iteration:
i = 5
j = 5
a[j-1] = X
a[j] = B
since a[j-1] > a[j], exchange a[4] with a[5]
Array : A,C,Q,S,B,X,T

a[j-1] = A
a[j] = B
since a[j-1] < a[j], break from inner loop
Number of comparisons in 5th Iteration = 5
After 5th Iteration:

6th Iteration:
i = 6
j = 6
a[j-1] = X
a[j] = T
since a[j-1] > a[j], exchange a[5] with a[6]
Array : A,B,C,Q,S,T,X
