wow your solution is better than mine

practice more

goood job

very nice solution! I want to be able to do the same

Nice, I like that use of the dictionary !

Same here, I literally copied this solution and it still doesn't pass the big numbers test

This is what I had, it puts out an infinite loop on the big numbers

The same thing happened to me

looooook

I don't get it, can someone explain pls

the best way to do it

bruh

str turns the integer into a string. It's the difference between the number 55 and the string "55". To check whether the string "5" is within the number, you first have to convert the number to a string by using str.

Thanks !
