Solution: Binary Search

Understand how to implement the binary search algorithm to locate a target value in a sorted array by iteratively narrowing search boundaries. Learn to apply this modified binary search method to solve search problems efficiently, analyzing time and space complexity.

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.

Constraints:

  • 11\leq nums.length \leq 10310^3 ...
