Coding Quiz - Implement Binary Search
Based on what you have learned so far, implement the binary search
algorithm yourself.
Given a sorted list of numbers
and a target value
, you need to write a function that uses the binary search algorithm to find the index of the target value
.
If the target value is not present in the list, return -1
.
Write the Code
def solution(numbers, target): # Write your code here return
Constraints
-
numbers
are sorted in ascending order. -
numbers
do not contain duplicate values. -
target
is an integer.
