I have a string of fixed width where every position has to do with some data. I will have to match this string to others and given different weights, see how equal they are.

is there any advantage efficiencywise to having that data from a string in multiple columns instead of a single column?

ie. Situation 1 column:

Column 1: abcd

Situation 4 columns:

Column 1:a
Column 2:b
Column 3:c
Column 4:d

Thanks!
