Binary search if element not found
WebFeb 28, 2024 · Binary searches are efficient algorithms based on the concept of “divide and conquer” that improves the search by recursively dividing the array in half until you either find the element or the list gets narrowed down to … WebGiven a sorted integer array containing duplicates, count occurrences of a given number. If the element is not found in the array, report that as well. For example, Input: nums [] = [2, 5, 5, 5, 6, 6, 8, 9, 9, 9] target = 5 Output: Target 5 occurs 3 times Input: nums [] = [2, 5, 5, 5, 6, 6, 8, 9, 9, 9] target = 6 Output: Target 6 occurs 2 times

WebMar 18, 2024 · If the array is infinite, that means we don’t have proper bounds to apply binary search. So in order to find position of key, first we find bounds and then apply binary search algorithm. Let low be pointing to 1st element and high pointing to 2nd element of array, Now compare key with high index element, WebBinary Search is one of the fastest searching algorithms. It is used for finding the location of an element in a linear array. It works on the principle of divide and conquer technique. Binary Search Algorithm can be applied only on Sorted arrays. So, the elements must be arranged in- Either ascending order if the elements are numbers.
