XOR Interview Problem Explained | LeetCode 1486

In this video, we solve LeetCode 1486 – “XOR Operation in an Array” step by step.

You’ll learn:

* What XOR (^) operation means
* Basics of bit manipulation
* How to generate array values efficiently
* Optimized solution using a single loop

Problem:
You are given:

* n (size of array)
* start (starting value)

Generate the array:
nums[i] = start + 2 * i

Return the bitwise XOR of all elements in the array.

⏱ Time Complexity: O(n)
💾 Space Complexity: O(1)

💡 Key Concept:
Use XOR (`^`) to combine all generated elements efficiently.

XOR Rules:

* a ^ a = 0
* a ^ 0 = a
