🔍 Problem of the Day
👉 Find Three Consecutive Integers That Sum to a Given Number (LeetCode 2177)
In this video, we solve a simple yet powerful math-based problem using an optimized approach.
---
🧠 Key Concept
If a number can be written as the sum of 3 consecutive integers, then:
* It must be divisible by 3
* The numbers will be: (x-1, x, x+1) where x = num / 3
---
⚡ Approach
✔️ Check if num % 3 == 0
✔️ If yes → return {x-1, x, x+1}
✔️ Else → return empty array
