Problem: Search Insert Position

Explore how to use binary search to locate a target or determine its insert position in a sorted array. Understand how the algorithm narrows the search space to achieve logarithmic time complexity and maintain array order. This lesson guides you through implementing an efficient search insert position solution in JavaScript.

Statement

You are given a sorted array nums consisting of distinct integers, along with an integer target. If target exists in nums, return its index. Otherwise, return the index at which target would need to be inserted to maintain the array’s sorted order.

Your solution must achieve O(logn)O(\log n) runtime complexity.

Constraints:

  • 11 \leq nums.length 104\leq 10^4 ...
