Some simple C++ tips for beginners:↵
↵
1 Use long long when values can be large. ↵
2 Always check edge cases. ↵
3 Read the constraints before choosing an algorithm. ↵
4 Avoid O(n²) when n can be very large. ↵
5 Test your solution with small cases before submitting. ↵
↵
Good luck and have fun coding! ↵
