Strange code
Difference between en1 and en2, changed 0 character(s)
During Codeforces Round 966 Div.3, I was writing a solution to problem B.  During the contest, I had come up with this code:  https://ide.usaco.guide/O4IVEpEkaUruFQ_sq5c.  ↵

However, it gave me a "YES" for the fourth subcase in the sample test case.  I searched everywhere in the code for what might be giving an answer like this, but I found nothing.  ↵

To fix this, I tried what seemed like a completely arbitrary thing:  create a vector of the bus seatings beforehand, then figure out if the seating is valid.  To my complete surprise, this worked, as can be seen in this submission: https://codeforces.net/contest/2000/submission/276167020.  ↵

I still can't identify what the major difference between the two codes is, so I was wondering if anybody could help me find the error.
