it took me some time until i figured the -1 and -2 to get the second form the last

i did that throws error had to check for string len 2 or 3

Same! TIL

A quick word of thanks - I actively learned from this. I appreciate all of you who put this answer in and helped make my code better. :)

i liked this pin

crazy xD

😳

Here you sort ALL the 50 millions element and after you had to compare the digit (not linear for sur).

But all you have to do is to look element by element and find the first one who is not asc (linear).

Sorry for my english

damn, did the same thing but replaced -1 with len(arr) -1, yours is much simpler lol

Wow.. I made mine way more complicated

This is an excelent use of String Slicing in Python

what is the use of underscore?

i didn't know that range function return a list . nice
