/*

Primary Colors Addition

The program must accept a character matrix of size R*C representing the primary colors (R, G, B) as the input. The value of C is always even. The program must fold the given color matrix vertically and print the resulting colours based on the following conditions

1) Red + Red = Red
2) Green + Green = Green
3) Blue + Blue = Blue
4) Green + Blue = Cyan (repres  ented as C)
5) Red + Blue = Magenta (represented as M)
6) Red + Green = Yellow (represented as Y)

Boundary Condition(s):
2 <= R, C <= 50

Input Format:
- The first line contains R and C separated by a space.
- The next R lines, each contains C characters separated by a space.

Output Format:
- The first R lines, each contains C characters separated by a space.

Example Input/Output 1:
Input:
5 6
R G B B G B
B R B G R G
R G R R B R
R R G R G R
G R G R B R

Output:
M G B
C R C
R C R
R Y Y
G R M
