WebThe recursive method of binary search follows the divide and conquer approach. Let the elements of array are - Let the element to search is, K = 56 We have to use the below formula to calculate the mid of the array - mid = (beg + end)/2 So, in the given array - beg = 0 end = 8 mid = (0 + 8)/2 = 4. So, 4 is the mid of the array. WebApr 9, 2024 · Recursive Binary Search in Java #recursion #binarysearch #algorithm #java WebMay 23, 2024 · Binary Search Simply put, the algorithm compares the key value with the middle element of the array; if they are unequal, the half in which the key cannot be part of is eliminated, and the search continues for the remaining half until it succeeds. Remember – the key aspect here is that the array is already sorted. cheshfest
