I'm too lazy to look into it right now, but (Update:finally, i wasn't) it does not work.
Use this test input:
Pick a card from below.
(I choose 10 of s col 4 / row 1 below)
 2d Ah 5h 10s
 Qc 3h As 7c
 Kc 6d 9s Js
 8h Qd 3d 10c
Which column is your card in (1-4, left-to-right)? 4
   
 2d Qc Kc 8h
 Ah 3h 6d Qd
 5h As 9s 3d
 10s 7c Js 10c
Which row is your card in (1-4, top-to-bottom)? 4
Your card is: 10c
Oops! This can't work because you'll always get rows == cols. It will only work on cards that are on 1/1, 2/2, 3/3, and 4/4, as they don't move... But it's just a small glitch...
