Matrix sort

[Sibuns]

Hey!
I have one problem with sorting matrix. So i want to sort the first row in matrix alphabetically and than copy all the values of other rows to matching char.

Example:

R E D
b g s
a v g
a a

sorting first row, and copy other char to the matching char

D E R
s g b
g v a
a a

Ty for your help!

So, other than row 4 (aa) it looks as though you exchange columns based on the results of sorting the first row. Is that the effect you're after?

If so, then the swap during the sort needs to be for each row all at the same time.

 swapColumns(matrix, c1, c2)
 {
   for each row in matrix
     swap(matrix[row][c1], matrix[row][c2]);
 }
