Inbuilt binary search in python

WebThis is a Python program to implement binary search without recursion. Problem Description The program takes a list and key as input and finds the index of the key in the list using binary search. Problem Solution 1. Create a function binary_search that takes a list and key as arguments. 2. WebCreate a function binary_search () which accepts 4 parameters (array, low, high, a). Declare two variables to store the highest and the lowest values in the list. Then Follow step 4 until the lowest and highest meet each other: mid = (low + high)/2 if (a == arr [mid]) return mid else if (a > arr [mid]) // a is on the right side low = mid + 1
