Webbinary search is simple to write using a loop. using recursion is unnecessary. – DwB Sep 25, 2013 at 18:45 1 If you must use recursion, which I try to avoid because I see it as terrible (note that this is an opinion), the do not pass the array, instead pass the array, a left index and a right index; the indices identify the boundary of the search. WebBinary Search Algorithm in C++ using Recursive Approach. a) Take an array, initial index, size, and search key. b) Find the middle term. c) if middle term == search key then return index. d) if middle term > search key then apply recursive call on the first half of the array. e) else apply recursive call on the second half of the array. guy sitting on toilet

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.
