you can only use dfs , but don't forget to sort the team . When I
use sorting as from short to long , I got TL , but when from long to
short , only 0.02s !

I sort from long to short, but still Time Limited Exceeded.
Can you tell me why?

I was expecting TLE, because I use O(N^N), but in fact got AC in 0.015
I wonder if people who get TLE are doing something like O(N^N^N^π^e) lol
