curprev 08:3408:34, 28 June 2024 Neiljohnlord talk contribs 10,901 bytes −30 →Python: The class has a method that returns the last number and the reversed order remaining numbers. In the for loop the remaining numbers is however reversed again which results in an incorrect answer. The github repository that is referenced does not reverse the remaining numbers in the function that splits it up. I changed the code to more allign with the reference while returning the correct answer. undo

curprev 23:1023:10, 14 June 2024 Mcbenne2 talk contribs 10,920 bytes +30 The python example for calculating was incorrect. It gave an incorrect answer on on an odd number of digits because it worked from left to right instead of right to left. Reversing the remaining numbers fixes. undo
