Solution: Binary Search

Understand how to apply the binary search algorithm to locate a target value in a sorted array by repeatedly dividing the search space. Learn the iterative method to adjust search boundaries and achieve efficient search performance with logarithmic time complexity and constant space usage.

Statement

We are given an array of integers, nums, sorted in ascending order, and an integer value, target. If the target exists in the array, return its index. If the target does not exist, return -1.
