# [Community Puzzle] Road Trip

Hm, does anyone have debugging suggestions for validator 4, it seems to be testing a scenario not covered by the test cases.
Thanks in advance.

I checked the puzzle ā¦

Test and validator 4 (Necessary fake friends) are similar with same number of friendsā¦

Thanks for replying. I guess what makes a difference is the distribution of the friends, not their number.

Anyone else stuck on the last test (too many friends)? My solution returns ā11505825ā while the correct solution is ā12211143ā. Iām passing all the other tests and canāt break through the last one. Unfortunately, I cannot properly debug it, because if I add print() statements, it times out.

i donāt understand some cases in this puzzle.
For instance the āMANY REAL FRIENDā
SOlution is 21515517, so i assume you should leave with 422 friends, for a cost per person of 1087.9 (rounded)

what about leaving with 423 friends, for a total hapiness of 21527121, and a cost per person of 1086.9

or leaving with 498 friends, for a cost per person of 975.6 and a hapiness of 25259954 (better than solution)

am I totally missing something ?

If you want to leave with 423 friends you canāt cause thereās only 422 of them who could afford it.
If you want to leave with 498 friends you canāt cause thereās only 450 of them who could afford it.

my code is working as well in your testcase, but idk original testcase is wrong -_-

Hi, all my tests cases are working, and all validator are working except first one, I have no clue. Any idea ?

You may PM me your code to let me have a look.
