Solution: Find the Closest Number
Explore how to efficiently find the closest number to a target value in a sorted array using a binary search approach. This lesson guides you through handling boundary conditions, applying divide and conquer strategy, and understanding the time complexity improvements from O(n) to O(log n). You'll gain practical skills in implementing optimal search algorithms suitable for coding interviews.
We'll cover the following...
Solution#1
A simple solution to this problem can be to traverse through the array while computing the minimum absolute difference of each array element with the target. Finally, return the element that has the minimum absolute difference.
Time complexity
Since we have to go through each element one by one and compute its absolute difference, this solution is implemented in time. ...
