Check if Number is a Sum of Powers of Three - Leetcode 1780 - Python | Soumil Speaks

📌 Check if Number is a Sum of Powers of Three | LeetCode 1780
🔥 Problem Statement:
Given an integer n, determine whether n can be expressed as a sum of distinct powers of three.

🔹 Mathematical Insight:
A number n can be represented as a sum of distinct powers of 3 if and only if its ternary (base-3) representation contains only 0s and 1s (i.e., no 2s).

🚀 Solution Approach:
✅ Greedy Approach: Start from the highest power of 3 and check if we can subtract it from n.
✅ Ternary Representation: Convert n to base-3 and check if it only contains 0s and 1s.

🔗 Topics Covered:
✔️ Greedy Algorithm
✔️ Ternary (Base-3) Representation
✔️ Powers of Three
