A. Competitive Programmertime limit per test1 secondmemory limit per test256 megabytesinputstandard inputoutputstandard outputBob is a competitive programmer. He wants to become red, and for that he needs a strict training regime. He went to the annual meeting of grandmasters and asked n of them how much effort they needed to reach red."Oh, I just spent x_i hours solving problems", said the i-th of them. Bob wants to train his math skills, so for each answer he wrote down the number of minutes (60 \cdot x_i), thanked the grandmasters and went home. Bob could write numbers with leading zeroes — for example, if some grandmaster answered that he had spent 2 hours, Bob could write 000120 instead of 120.Alice wanted to tease Bob and so she took the numbers Bob wrote down, and for each of them she did one of the following independently:   rearranged its digits, or  wrote a random number. This way, Alice generated n numbers, denoted y_1, ..., y_n.For each of the numbers, help Bob determine whether y_i can be a permutation of a number divisible by 60 (possibly with leading zeroes).InputThe first line contains a single integer n (1 \leq n \leq 418) — the number of grandmasters Bob asked.Then n lines follow, the i-th of which contains a single integer y_i — the number that Alice wrote down.Each of these numbers has between 2 and 100 digits '0' through '9'. They can contain leading zeroes.OutputOutput n lines.For each i, output the following. If it is possible to rearrange the digits of y_i such that the resulting number is divisible by 60, output "red" (quotes for clarity). Otherwise, output "cyan".ExampleInput

NoteIn the first example, there is one rearrangement that yields a number divisible by 60, and that is 360.In the second example, there are two solutions. One is 060 and the second is 600.In the third example, there are 6 possible rearrangments: 025, 052, 205, 250, 502, 520. None of these numbers is divisible by 60.In the fourth example, there are 3 rearrangements: 228, 282, 822.In the fifth example, none of the 24 rearrangements result in a number divisible by 60.In the sixth example, note that 000\dots0 is a valid solution.
