While this made sense I quickly realized I would still have the step of sorting based on the keys. This should still have worked but since the arrays have the same indices I didn't really need to combine them into a hash. I sorted the popularity array and outputted the indices in sort order (not the values): -```my @pop_sort_idx = sort { $popularity[$a] <=> $popularity[$b] } 0 .. $#popularity;``` +``` +my @pop_sort_idx = sort { $popularity[$a] <=> $popularity[$b] } 0 .. $#popularity; +``` With that I return an array of the languages in sort order using the inputted langage array in the order of the sorted popularity: -```@lang[@pop_sort_idx];``` +``` +@lang[@pop_sort_idx]; +``` ## Task 2: Largest of Three |
