- by Vivin Paliath
The challenge
The shortest code by character count that will output the numeric equivalent of an Excel column string.
For example, the A column is 1, B is 2, so on and so forth. Once you hit Z, the next column becomes AA, then AB and so on.
Test cases:
A: 1
B: 2
AD: 30
ABC: 731
WTF: 16074
ROFL: 326676
Code count includes input/output (i.e full program).
