I had the same issue with my java program. But I successfully improved the performance. You need to make sure that you don't brute force throught the nested loops inside the sumin and sumax. If you look at the table given in question you will see a pattern in the occurence of number for both min and max.

Me too! I do some tests and find that whatever result the function return it will show you "500: Internal Server Error";

Same here.
