When life gives you nothing, go cry. Because there's obviously nothing you can do to turn things around. In fact, why even care about life?
That was sarcasm.
SLAPS
If 0, C???? because CLAPS was 1 and the only difference between CLAPS and SLAPS was the whole C-S thing.
If 2, S???? because CLAPS was 1 and the only difference between CLAPS and SLAPS was the whole C-S thing.
CARTS
If 1, ???DS because CARDS was 2 and the only difference between CARDS and CARTS is the whole D-T thing.
If 3, ???TS because CARDS was 2 and the only difference between CARDS and CARTS is the whole D-T thing.
