    /*

         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

            -check for some values which might be incorrect --> ((long)sqrt(n) does not always give the max number t*t<=n, adjust t).

         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
