SISolving the “Single Number” problem doesn’t always require complex algorithms — sometimes even a simple brute force approach works.
In this reel, we used:
Brute Force Approach
– Compare every element with every other
– Simple to understand
– But takes more time (O(n²))
Better Approach (Using Frequency Map / Hashing)
– Count occurrences
– Return the number that appears only once
– Much faster (O(n))
This is how DSA works:
👉 Start with the simplest logic
👉 Improve step by step
👉 Then later move to advanced ideas like XOR and Bit Manipulation
