/*
Random stuff to try when stuck:
-if it's 2C then it's dp
-for combo/probability problems, expand the given form we're interested in
-make everything the same then build an answer (constructive, make everything 0 then do something)
-something appears in parts of 2 --> model as graph
-assume a greedy then try to show why it works
-find way to simplify into one variable if multiple exist
-treat it like fmc (note any passing thoughts/algo that could be used so you can revisit them)
-find lower and upper bounds on answer
-figure out what ur trying to find and isolate it
-see what observations you have and come up with more continuations
-work backwards (in constructive, go from the goal to the start)
-turn into prefix/suffix sum argument (often works if problem revolves around adjacent array elements)
-instead of solving for answer, try solving for complement (ex, find n-(min) instead of max)
-draw something
-simulate a process
-dont implement something unless if ur fairly confident its correct
-after 3 bad submissions move on to next problem if applicable
-do something instead of nothing and stay organized
-write stuff down
Random stuff to check when wa:
-if code is way too long/cancer then reassess
-switched N/M
-int overflow
-switched variables
-wrong MOD
-hardcoded edge case incorrectly
Random stuff to check when tle:
-continue instead of break
-condition in for/while loop bad
Random stuff to check when rte:
-switched N/M
-long to int/int overflow
-division by 0
-edge case for empty list/data structure/N=1

Random stuff to try when stuck:
- use bruteforcer
- check for n = 1, n = 2, so on
-if it's 2C then it's dp
-for combo/probability problems, expand the given form we're interested in
-make everything the same then build an answer (constructive, make everything 0 then do something)
-something appears in parts of 2 --> model as graph
-assume a greedy then try to show why it works
-find way to simplify into one variable if multiple exist
-treat it like fmc (note any passing thoughts/algo that could be used so you can revisit them)
-find lower and upper bounds on answer
-figure out what ur trying to find and isolate it
-see what observations you have and come up with more continuations
-work backwards (in constructive, go from the goal to the start)
-turn into prefix/suffix sum argument (often works if problem revolves around adjacent array elements)
-instead of solving for answer, try solving for complement (ex, find n-(min) instead of max)
-draw something
-simulate a process
-dont implement something unless if ur fairly confident its correct
-after 3 bad submissions move on to next problem if applicable
-do something instead of nothing and stay organized
-write stuff down
Random stuff to check when wa:
-if code is way too long/cancer then reassess
-switched N/M
-int overflow
-switched variables
-wrong MOD
-hardcoded edge case incorrectly
Random stuff to check when tle:
-continue instead of break
-condition in for/while loop bad
Random stuff to check when rte:
-switched N/M
-long to int/int overflow
-division by 0
-edge case for empty list/data structure/N=1
