Largest int from concatenated ints: Difference between revisions

===Sort on comparison of concatenated ints method===

===Compare repeated string method===

<lang ruby>def icsort nums

maxlen = nums.max.to_s.length

nums.map{ |x| x.to_s }.sort_by { |x| x * (maxlen / x.length + 1) }.reverse

end

[[54, 546, 548, 60], [1, 34, 3, 98, 9, 76, 45, 4]].each do |c|

p c # prints nicer in Ruby 1.8

puts icsort(c).join

end</lang>

;Output as above.
