[algogeeks] Re: Google Interview Question
here's efficient oneliner without any string manipulation divide every number by 10^(log10(x).ceil) sort convert back to original numbers join array into string there are edge-cases where this doesn't work but they can be dealt with easily - have to go back to work :) -- You received this message because you are subscribed to the Google Groups Algorithm Geeks group.

simplest algo: find a node with max depth M and go up tree calculating max depth of all upper branches that do not contain M until reaching root node -- You received this message because you are subscribed to the Google Groups Algorithm Geeks group.

Re: [algogeeks] Google Interview Question
some explanation say we have numbers 2 3 5 78 divide all by something to get 0.2, 0.3, 0.5, 0.78 simple sort will give you 0.78, 0.5, 0.3, 0.2 multiply all numbers to get original ones 78 5 3 2 join 78532 -- You received this message because you are subscribed to the Google Groups Algorithm Geeks group.

Re: [algogeeks] Google Interview Question
possible fix for 100 10 edgecases would be to simply array.map{|x| x*10+1}
and then get rid of that after sorting

Re: [algogeeks] Google Interview Question
@Sunny i explained how to deal with edgecases right after my post 1, 101 - 11, 1011 11, 1011 - 0.11, 0.1011 sort - 0.11, 0.1011 restore - 1, 101 join - 1101 i can't think of any fail examples anymore -- You received this message because you are subscribed to the Google Groups Algorithm Geeks group.

Re: [algogeeks] Google Interview Question
@halo check my previous messages we multiply every element by 10 and add 1 90, 9 - 901, 91 901, 91 - 0.901, 0.91 sort - 0.91, 0.901 revert - 9, 90 join - 990 -- You received this message because you are subscribed to the Google Groups Algorithm Geeks group.

[algogeeks] Re: Google Interview Question
so here's oneliner code in ruby:
a.map{|x| x=x*10+1; -x/10.0**Math.log10(x).ceil}.sort.map{|x|
(-x).to_s[2..-2]}.join
