/* stuff you should look for
* int overflow, array bounds
* special cases (n=1?)
* do smth instead of nothing and stay organized
* WRITE STUFF DOWN
* DON'T GET STUCK ON ONE APPROACH (TRY DP INSTEAD OF GREEDY AND VICE VERSA)(DONT FORGET SORTING)
* TRY ALL STRATEGIES
* DO NOT READ EDITORIALS BEFORE TRYING REALLY HARD!
* careful references in recursion
* careful copying when doing vectors esp in loops and functions
* careful long long int and mod always OMG
* careful return types of std such as int(ceil)
* WATCH OUT GOING OVER MAX thru operations spam mod
* vectors overflow arrays do NOT
* cout endl lol
* lower bound is first greater or equal
* upper is first greater
* if TLE play around with compiler
* use static is helpful!!
* take note of test stuff that need to be changed before submission
* careful when u use garbage from abroad
* careful modeling stuff as num going below 0 above n
* number theory infinite due to multple of each other
* careful not finding stuff in dictionaries
* stupid cout precision and sci notations
* in sets, rbegin() or --end() for last
* careful multiset removal just use heapp
* no segment trees if partial mins are needed, use sparse table
* in combinatorics log matters esp in that dp, and think v carefully
* NEVER INPUT DOUBLES
* fraction class or multiplication tricks?
* omg dont forget to flush when debugging
* watch out for bitwise operations order of operations
* PQ Greater top is smallest and Less top is largest
