I am trying to solve LCMSUMH and i see RANKS have 17 accpetted submition. But there is something very strange that all of sumitted time (https://www.spoj.com/ranks/LCMSUMH/) are not real submition. Beacause i have checked every user_id but i do not found anyone solved this problem. Please check help me, does this problem is correct?
I think it’s not showing in the users’ Solved Problem list because it’s a tutorial.
