Problem Statement
Check divisibility by 11 using digit positions rule.
Input Format
One non-negative integer n.
Output Format
YES or NO.
Constraints
0
Code Solution
This explanation is written for learning purposes and to help beginners understand the concept clearly.
Compute alternating sum of digits (odd positions minus even positions). If the difference is divisible by 11, print YES.
Common Mistakes
- Misreading input/output format.
- Not handling constraints and edge cases.
- Off-by-one errors in loops.
- Forgetting to reset variables between test cases (if any).
