1st: In yesterday's contest I got [FST](https://mirror.codeforces.com/contest/1546/submission/122102564) on B on T.C-11, and after I reviewed it I found out that I was mistakenly running loop till n where I should run it till n-1 only, but ironically pretests passed without RTE, so could anyone explain why RTE didn't occur...↵

2nd: As per the [blog](https://mirror.codeforces.com/blog/entry/70237#:~:text=So%20we%20won't%20see,if%20its%20arguments%20are%20equal.),) the comparator should return false, and as per my [code](https://pastebin.ubuntu.com/p/thF8DGdwqV/), it would be returning false, but doing this showed WA on CSES Projects DP question and as I entered (>=) it got AC.↵
So, what's the logic behind this flaw, or is it due to my false understanding.↵

Thanks for your help!
