Bob 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.

翻译中…

"Oh, I just spent $x_i$ hours solving problems", said the $i$-th of them.

翻译中…

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.
翻译中…

This way, Alice generated $n$ numbers, denoted $y_1$, ..., $y_n$.

翻译中…

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).

Input

翻译中…

The first line contains a single integer $n$ ($1 \leq n \leq 418$) — the number of grandmasters Bob asked.

翻译中…

Then $n$ lines follow, the $i$-th of which contains a single integer $y_i$ — the number that Alice wrote down.

翻译中…

Each of these numbers has between $2$ and $100$ digits '0' through '9'. They can contain leading zeroes.

Output

翻译中…

Output $n$ lines.

翻译中…

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".

Note

翻译中…

In the first example, there is one rearrangement that yields a number divisible by $60$, and that is $360$.

翻译中…

In the second example, there are two solutions. One is $060$ and the second is $600$.

翻译中…

In the third example, there are $6$ possible rearrangments: $025$, $052$, $205$, $250$, $502$, $520$. None of these numbers is divisible by $60$.

翻译中…

In the fourth example, there are $3$ rearrangements: $228$, $282$, $822$.

翻译中…

In the fifth example, none of the $24$ rearrangements result in a number divisible by $60$.

翻译中…

In the sixth example, note that $000\dots0$ is a valid solution.
