WebOct 15, 2024 · Binary Search uses three different variables — start, end and mid. These three variables are created as pointers which point to the memory location of the array indices. Due to this, binary search is extremely efficient with space. The space complexity of iterative binary search is O (1). For recursive implementation, it is O (log N). WebThe base of binary search was that you have reached a particular element and since the array is sorted, the elements on the left would be smaller and the right ones would be larger. According to what you have to search, either you go rightwards and discard / ignore the left array or vice-versa.
