**The Problem**

Kabir vai is a great programmer. He is invited to a birthday function. But he started to feel boring. The place was decorated with small lights which were blinking and changing colors with each blink. At the first blink a light colored green, then blue with next blink, then red and yellow at last. See the sequence:

*Green=>Blue=>Red=>Yellow.*

Kabir vai started to count the blinks and at a certain count he suddenly stopped. Can you tell which color was on the light then?

**Input**

Input will contain an integer N, 1<=N<= – 1, (number of blinks Kabir vai counted) in each line.

**Output**

For each input, output which color is on the light in a line. See sample input and output below.

**Sample Input**
