<prompt> Tumia algorithm ya utafutaji wa binary.arr: 1, 2, 4, 6, 8, 10, 11, 15, x: 8  <response>: Here is an implementation of a binary search algorithm in Python that you can use to find whether the element x is present in the list arr:pythondef binary_searcharr, x: low 0 high lenarr - 1 mid 0 while low high: mid high low 2 Check if x is present at mid if arrmid x: low mid 1 If x is greater, ignore left half elif arrmid x: high mid - 1 If x is smaller, ignore right half else: return mid If we reach here, then the element was not present in the list return -1arr 1, 2, 4, 6, 8, 10, 11, 15x 8result binary_searcharr, xif result ! -1: printfElement is present at index resultelse: printElement is not present in the listThe result will be : Element is present at index 4 since the element 8 is present at index 4 in the given list arr.
