It might have also been the fact that I forgot to check the commands MOV and TRN for the character starting at the 6th position (which should be a number for both) as being a digit. It now runs much faster in SoloLearn! NOTE: I can comment my code for those wanting to learn, but I'm too lazy to do it for myself. Let me know in the comments if that is something you want to see. */ /* Code By: Zeke Williams Date: December 8, 2018 **********INSTRUCTIONS********** Input any commands you want, or enter none for random commands. The program will use your commands and then make random commands until the total number of cammands is 20. ******************************** Description: I found some time to do a contest code, even though it wasn't in time for the actual contest. For now, I am not accepting inputs for this code. However, it should have that feature in the future.
