NettetBinary Search Algorithm – Iterative and Recursive Implementation Given a sorted array of n integers and a target value, determine if the target exists in the array in logarithmic time using the binary search algorithm. If target exists in the array, print the index of it. For example, Input: nums [] = [2, 3, 5, 7, 9] target = 7 Nettet8. des. 2010 · public static int binarySearch (Comparable [] objArray,Comparable item) { int lower=0; int upper=objArray.length -1; You have this (this is java-like pseudocode, highly simplified and without error checking, you need to work the actual syntax details):

If 2^i is greater than the lenght of array, then set the upper bound to the length of the array. Do a binary search between Array [2^ (i-1)] and Array [2^i] The Code
Nettet25. feb. 2024 · Binary Search is a searching algorithm used in a sorted array by repeatedly dividing the search interval in half. The idea of binary search is to use the information that the array is sorted and reduce the time complexity to O (Log n).

Nettet12. jul. 2024 · The time complexity of the above algorithm is O(n) because we’re visiting each node exactly once. The space complexity is O(log n) because, I have used recursion here. Here are some more problems that can be solved using binary search algorithm. You can practice them to understand the algorithm better:
