Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.
Get started now by creating a new collection.
I am having a lot of failing tests during final attempt (Python). For example,
'pF@-`{vY=NlV#(#F<DF(G_gJFG]rT12320983' should equal 'p12320982F@1-26761748`{v93Y5=46000309NlV#(433847697#F<DF(G_gJ1FG]rT640000000010'
or
')m\\MJ@<@naY&}EI14142' should equal '14141)m\\4MJ@2535275<@na4771545Y&}EI6460000010'
What the hell is going on?

I think, such solution is not optimal due to O(N) performance. You are converting all elements in list to int even if element is int.
