Let P be a quick sort program to sort numbers in ascending order using the first element as the pivot. Let t1 and t2 be the number of comparisons made by P for the input [1 2 3 4 5] and [4 1 5 3 2] respectively. Which one of the following holds?
At1 = 5
Bt1 < t2
Ct1 > t2
Dt1 = t2
Answer: Option C
Explanation:When first element or last element is chosen as pivot, Quick Sort's worst case occurs for the sorted arrays.
In every step of quick sort, numbers are divided as per the following recurrence.
T(n) = T(n-1) + O(n)
As same sort program is used therefore t1=t2.

if (x<=list A[k])
j=k-1;
if (list A[k] <=x)
i =k+1;
} while (i <=j);
if (list A[k] == x)
return (k);
else
return -1;
