WebNov 17, 2011 · For Binary Search, T (N) = T (N/2) + O (1) // the recurrence relation Apply Masters Theorem for computing Run time complexity of recurrence relations : T (N) = aT … WebRecursion is a separate idea from a type of search like binary. Binary sorts can be performed using iteration or using recursion. There are many different implementations for each algorithm. A recursive implementation and an iterative implementation do the same exact job, but the way they do the job is different.

"WebThe recursive method of binary search follows the divide and conquer approach. Let the elements of array are - Let the element to search is, K = 56 We have to use the below formula to calculate the mid of the array - mid = (beg + end)/2 So, in the given array - beg = 0 end = 8 mid = (0 + 8)/2 = 4. So, 4 is the mid of the array. " - Recursive equation for binary search
