Codeforces Triangle Problem (6A) | Day 17 | Beginner → Grandmaster Series

🚀 Day 17 of the Codeforces Beginner to Grandmaster Series In this video, we solve Triangle – Problem A from Codeforces Beta Round 6. The problem gives 4 sticks, and we need to determine whether any 3 of them can form a triangle. Possible outcomes: TRIANGLE → if any 3 sticks satisfy the triangle inequality SEGMENT → if they form a degenerate triangle IMPOSSIBLE → if neither is possible 💡 Key Idea For three sides a, b, c: Triangle → a + b is greater than c Segment → a + b = c Otherwise impossible Since we have 4 sticks, we check all combinations of 3 sticks. This is a classic implementation + math problem perfect for beginners starting competitive programming.
