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
