this was hard for me as a beginner, took me like 5 hours to figure out
Smart but dangerous. Ofc its 8 kyu kata and we shouln't be worried about security aspects.
8 kyu and I can't complete this task :\
It's one of the oldest katas on the site so ranking/difficulty grading is a bit out of date.
Besides, if you think it is too easy; why not try to solve it in O(1) rather than your O(n) solution which times out for inputs ~ 100,000,000 ?
100,000,000
It should be 8 kyu instead 6 kyu
