// My code is not working!!! Try these fixes:
// 1. Check for overflow (uncommenct #define int long long)
// 2. Check for array bounds
// 3. Check for array indexes, 1-indexed or 0-indexed?
// 4. Check for special cases (n=1?)
// 5. Check for multiple test cases (remember to clear global variables)
// 6. Check the limits of your data types maybe l <= r, maybe 0 <= n...
// Getting TLE? Try these fixes:
// 1. Delete the line: #define int long long
// 2. Use array instead of vector
// Getting WA? Good luck, you're on your own
