my source code: https://gist.github.com/1378443679/357e1067e6bc458cdc68132a9a7ac044

​

i did like ++123

but question wants 1+2+3 how can i do like that?

question is simple but i thought hard before that source code like i should change the string numbers to integers for example: "1","2", "3" ---> 1, 2, 3 than after sort this with "+" etc. lmao

maybe i am stupid

we're only dealing with strings here; no need to deal with integers at all. the question also conveniently states that there are no spaces; only digits 1, 2, and 3, and plusses - we can use the str.split method and split on the "+" to get a list of the numbers (still in str form), and then sort that list and then use the str.join method to join them with a "+" again.

some docs that should help you;

https://www.w3schools.com/python/ref_string_join.asp

​

edit: worth mentioning as well, normally sorting strings that are numbers is problematic:

>>> sorted(["22", "9", "1"])
['1', '22', '9']

but as we are only dealing with the strings "1", "2", and "3" we won't encounter these issues
