K. 2018
Given a,b,c,d, find out the number of pairs of integers (x,y) where a ≤ x ≤ b,c ≤ y ≤ d and x·y is a multiple of 2018.

B. Higher h-index
The h-index of an author is the largest h where he has at least h papers with citations not less than h.
Bobo has no papers and he is going to publish some subsequently. If he works on a paper for x hours, the
paper will get (a·x) citations, where a is a known constant. It’s clear that x should be a positive integer.
There is also a trick – one can cite his own papers published earlier.
Given Bobo has n working hours, find the maximum h-index of him.
