/*
problems with mod or small constraints are DP (2d,3d) or combo
ascii: 1=49 a=97 A=65
check edge cases and constraints CHECK FOR JUST ONE ELEMENT OR SAME NUMBERS ETC
always think about reversing a process
see if theres any dumb tricks if youre not getting it: like only having to check small values or sth
(a-b)modm = (a%m+(m-b%m))%m
mark visited after adding to queue
think about transforming representations of graphs, if some graph is too big to be represented, think about bipartite
representation, if its too small maybe you can expand according to problem to make it easier
you can also bfs on pairs of nodes, different representations of nodes etc etc
lower bound can give beyond end also (check segfaults etc if using)
many smol vectors are slowwww, use std:array instead
to search for and remove particular things fastly just use multiset, like u can use prefix multiset and find closest
value of something also like so many applications in just logn time
READ ALL FUCKING SAMPLES, READ EVERYTHING BEFORE PUTTING PEN TO PAPER, START FROM THE SIMPLEST SAMPLE
