Solve Later

Given a lowercase letter or a digit as input, return the row where that letter appears on a standard U.S. QWERTY keyboard and its position starting from the leftmost digit or letter on that row.

Examples:

 Input  key = 'a'
 Output r = 3
        c = 1

 Input  key = '0'
 Output r = 1
        c = 10

 Input  key = 'y'
 Output r = 2
        c = 6

I'm curious: why did you include the [1 1]'s in your value set?

Hi, Heather. To be honest, this was an older version that I was using to test containers.Map, and ended up submitting by mistake.

Heather on 15 May 2013

You got the smallest answer by mistake? Cool!

Pedro on 16 May 2013

That would be something, wouldn't it? The mistake was copy-pasting this version, with the [1 1]s, instead of a version without them. They are not needed, as you noticed.
