Write a Python program for binary search.
Binary Search : In computer science, a binary search or half-interval search algorithm finds the position of a target value within a sorted array. The binary search algorithm can be classified as a dichotomies divide-and-conquer search algorithm and executes in logarithmic time.
def binary_search(item_list,item): first = 0 last = len(item_list)-1 found = False while( first<=last and not found): mid = (first + last)//2 if item_list[mid] == item : found = True else: if item < item_list[mid]: last = mid - 1 else: first = mid + 1 return found print(binary_search([1,2,3,5,8], 6)) print(binary_search([1,2,3,5,8], 5))
