WebBinary search completes in O (log N) time because each iteration decreases the size of the list by a factor of 2. Its space complexity is constant because we only need to maintain two pointers to locations in the list. Even the recursive solution has constant space with tail call optimization.

Iterative and Recursive Binary Search Algorithm

WebMar 20, 2015 · For a sorted and balanced binary tree, searching will take O (logN). The reason for this is that the search will only ever have to traverse one single path down the tree. A balanced tree with N nodes will have a height of log (N), and this explains the complexity for searching. Consider the following tree for example: 5 / \ 3 7 / \ / \ 1 4 6 8 WebThe recursive method of binary search follows the divide and conquer approach. Let the elements of array are -.
