Binary Search Time Complexity

EasyPython

Problem

What is the time complexity of the binary search algorithm?

Asked in the Technical interview stage. Implement iterative binary search to apply the complexity being tested.

Input and Output

Given a sorted list of integers nums in ascending order and an integer target, return the index of target, or -1 if it is absent. If duplicates exist, return any matching index.

Function signature: def binary_search(nums, target):

Constraints

  • 0 <= nums.length <= 10^5
  • -10^9 <= nums[i], target <= 10^9
  • nums is sorted in ascending order
  • If duplicates exist, returning any matching index is valid

Function Signature

def binary_search(nums, target):
