Sorting numbers with strings

-----------------------------------

err. I came across this, Ok, suppose i have something like this

Height  Name

123     Me
234     You
213     Someone
789     Friend

Now if I want to sort them, I can sort the numbers for example: 

123
213
234
789

but the problem asks for the names with them:

123    Me
213    Someone
234    You
789    Friend      

Can some1 help?  :cry:

i beleive you can just sort the list like any other string and it will come out in ascending order...

if all else fails, just put the two in two different arrays, and match em up.

I thought of that but how do i match em up. I mean i know how to match : 

for x : 1..upper(one)
     for s : 1..upper(two)
           if one(s) = two(s) then
           do blah
           end if
     end for
end for

but one is int and the other is string. any example?

After you're done sorting the numbers, just display them side by side . . 

var score : array 1 .. 4 of int := init (123, 234, 213, 789)
var name : array 1 .. 4 of string := init ("Me", "You", "Someone", "Friend")
for i : 1 .. 4
    put score (i), " ", name (i)
end for

-----------------------------------

you can sort *but* you have to ensure that all the numbers are of the same length by adding leading zeros. otherwise youre gonna have to split the array into 2 different ones and sort the numbers... when you swap 2 numebrs, swap the names aswell, then add the 2 arrays back together...
