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 - So, in the given array - beg = 0. end = 8. mid = (0 + 8)/2 = 4. So, 4 is the mid of the array. ... WebA recursive approach to linear search rst searches the given element in the rst location, and if not found it recursively calls the linear search with the modi ed array without the rst element. i.e., the problem size reduces by one in the subsequent calls. Let T(n) be the number of comparisons (time) required for linear search on an array of ...
