This code reads an integer and prints "YES" if the number is not divisible by 100 and not divisible by 10, otherwise it prints "NO". The condition checks if the number has a non-zero remainder when divided by 100 and also a non-zero remainder when divided by 10.
- The condition `a%100!=0&&a%10!=0` checks two separate things: whether the number is not a multiple of 100 and not a multiple of 10. Think about what happens for numbers like 20 or 110 — are they correctly handled by this logic?
- Consider what the problem might actually be asking. If the goal is to check something like whether the last two digits are non-zero, the current condition might be too strict or too broad. For example, a number like 5 passes, but a number like 1010 fails.
