Given the year number. You need to check if this year is a leap year. If it is, print `LEAP`, otherwise print `COMMON`. The rules in Gregorian calendar are as follows: - a year is a leap year if its number is exactly divisible by 4 and is not exactly divisible by 100 - a year is always a leap year if its number is exactly divisible by 400 **Warning.** The words `LEAP` and `COMMON` should be printed all caps. # Example input ``` 2012 ``` # Example output ``` LEAP
