Binary search in c++ recursive

WebBinary Search - Given 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. Input: nums = [-1,0,3,5,9,12], target = 9 Output: 4 WebJan 17, 2024 · Output: skeeG rof skeeG. Time Complexity: O(n) where n is size of the string Auxiliary Space: O(n) where n is the size of string, which will be used in the form of function call stack of recursion.
