C++ Program to Implement Binary Search using Iteration

WebBinary Search algorithm is used to search an element in a sorted array. Binary search works by comparing the value to the middle element of an array. If the value is found then index is returned otherwise the steps is repeated until the value is found. It is faster than linear search. Time complexity of Linear search is O (n). http://www.cprogrammingcode.com/2014/08/write-cc-code-to-implement-binary.html optometrist in sayville new york

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 WebNov 18, 2011 · With a binary search, you eliminate 1/2 the possible entries each iteration, such that at most it would only take 7 compares to find your value (log base 2 of 128 is 7 or 2 to the 7 power is 128.)
