"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 " - Binary search using recursion time complexity

Space complexity of iterative vs recursive - Binary Search Tree

WebGiven an array of integers nums which is sorted in ascending order, and an integer target, write a function to search target in nums. If target exists, then return its index. Otherwise, return -1. You must write an algorithm with O(log n) runtime complexity. Example 1: WebHow to find time complexity of recursive algorithms? Step 1: Identify input size and smaller subproblems We first identify the input size of the larger problem. Then we recognise the total number of smaller sub-problems. Finally, we identify the input size of smaller sub-problems. Step 2: Write recurrence relation for the time complexity
