How to approach this problem with binary search?
This problem has a tag binary-search and also on a2oj ladder it's given under binary search. Div2 : B http://codeforces.net/contest/492/problem/B
I solved it by plain sorting the array and finding the max difference as given in the editorial.
But, I would like to know how to solve this by binary search? Any hints/pointers please? I am curious to do this with a new approach.
