# Problem CGrotesquely Clean

If you look around the buildings of the University of Chicago, you will find many carved stone figures called grotesques (fun fact: these are commonly known as “gargoyles”, but a gargoyle is actually a type of grotesque and, specifically, one that spouts water). The grotesques have to be cleaned periodically, for which the university employs a Grotesque Cleaner called Hans Wasserspeier. Hans has recently taken on a young and enterprising apprentice, Graham R. Goyle, who suggested the Department of Computer Science could write a program that can help Hans and Graham determine whether a grotesque has to be cleaned or not.

The process to determine whether a grotesque has to be cleaned is very simple. First, Hans and Graham measure how dirty the grotesque is on ten different spots (each of these ten measurements will, ordinarily, have a value between 1 and 5). Then, if these ten measurements add up to a total of 30 or more, then the grotesque needs to be cleaned. Otherwise, it does not have to be cleaned.

However, sometimes, an specially dirty spot will result in a measurement having a value of 6. When this happens, the grotesque has to be cleaned, even if the measurements don’t add up to 30.

## Input

The input is composed of a single line, with ten integers, each separated by a single space. Each integer represents a measurement $m$ ($1 \leqslant m \leqslant 6$).

## Output

If the grotesque has to be cleaned, print CLEAN. If the grotesque does not have to be cleaned, print DO NOT CLEAN.
