Input parsing

[DragonHunt3r]

Implement input parsing as per the assignment description.

The input is formatted as follows:

n c m
k i1 i2 ... ik

Where

• n is the number of tiles (n >= 1).
• c is the number of tiles a cat can move in one turn (c >= 0).
• m is the number of tiles a mouse can move in one turn (m >= 0).
• k is the number of tiles with rocks (0 <= k <= n).
• i1 ... ik are the indices of the tiles with rocks (k elements long, 1 <= im <= n). Pay attention, these are 1-indexed.

All values should be valid integers.
