/* 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
  * IF MOD JUST MINUS IF NOT MUCH INCREASE
  * IF MOD REQUIRED THEN USE CONST LL
