I am not able to clear the speed criterion .I m having two loops(one loop inside another loop) in my code ,still it times out .
how can one optimise the execution time?can some one give me tips ??

should we read the input from using raw_input in python or can we intialise the function digitize(1) in the code itself.
I tried the code in my local machine it worked but when trying in this kata its failing. so please tell me how the input should be taken

ps: I am able to return the result like input :Digitize(125) returns [1,2,5] but still the solution is not being accepted in runtests.
But it was accepted in submit. don't know how to work around unknown error
