WebBinary search is a simple yet efficient searching algorithm which is used to search a particular element's position in a given sorted array/vector. In this algorithm the targeted element is compared with middle element. If both elements are equal then position of middle element is returned and hence targeted element is found. WebThe pseudocode is as follows: int binarySearch(int[] A, int low, int high, int x) { if (low > high) { return -1; } int mid = (low + high) / 2; if (x == A[mid]) { return mid; } else if (x < … images of skyline carsWebJul 27, 2024 · In a binary search algorithm, the array taken gets divided by half at every iteration. If n is the length of the array at the first iteration, then at the second iteration, the length of the array will be n/2. Again dividing by half in the third iteration will make the array’s length = (n/2)/2=n/ (2^k). images of slave houses
