WebBinary Search is a searching algorithm for finding an element's position in a sorted array. In this approach, the element is always searched in the middle of a portion of an array. … WebSep 23, 2024 · Then we apply binary search in one of the sub-array to find the given element. Algorithm. Take the array and key from user input. Traverse the array to find the pivot element. Divide the array into two subarrays around the pivot. Use binary search on one of the arrays by the following condition-Use the binary search in the left subarray.
