Searching in an Array where Adjacent Elements Differ by at Most k | Java Explanation
In this video, we will solve a popular interview problem:
How to efficiently search for an element in an array where the difference between adjacent elements is at most k.
You’ll learn:
✅ The problem statement and intuition behind it
✅ Step-by-step dry run explanation
✅ Optimized Java solution with code
This problem is frequently asked in coding interviews and helps you understand how to reduce unnecessary iterations using mathematical jumps instead of a linear scan.
📥 Example Input: arr = [20, 22, 23, 24, 25, 28, 30], x = 28, k = 2
📤 Output: Index = 5
