[Purdue-pm] How to sort one dimension of a 2d array

[Dave Jacoby]

So I fundamentally misunderstood the issue. OK.

This is the input, put into table form.

  7  0 25 10
  0  9  7 12
  3  2  1  0

This is the desired output.

  0  0  1  0
  3  2  7 10
  7  9 25 12

OK, now I get it. Kinda $x[$b][$a] instead of $x[$a][$b]. So, thinking 
of it as a table or matrix instead of an array of arrays. Not 
unreasonable, but computer science discourages thinking like that.
