User inputs an integer/string. I want to sort the digits/characters of this integer/string. How can I accomplish that in Ruby?

Question

I hope there is an easy way, but I couldn't find a method who does the work.

Examples:
47983 --> result: 34789
helloworld --> result: dehllloorw

Answer 1

Ok, i did a little bit of research and it seems like the following will do the trick:

n = gets # String input

z1 = n.chars.sort.join # String output
z2 = n.chars.sort.join.to_i # Integer output

or even the reversed number with:

z3 = n.chars.sort.reverse.join.to_i
