# TADM2E 4.33

From Algorithm Wiki

Apply binary search to find out transition point

Assume set indexes are zero based FindIndex(A): 1. low = 0, high =1 2. mid = (low + high)/2 3. if(A[mid] > mid) then Index will lie in left half of the array high = mid-1 Go to step 2. else if (A[mid] < mid) then Index will lie in right half of array low = mid + 1 else return mid
