Can someone help with the approach, please? Thanks!

We want to know.

ekzhang thank you for such an amazing interface.

I have a humble feature request which others may also find helpful. Option to switch to Fullscreen/Distraction Free/ Minimize problem description to a sidebar as we might not always want to see it at a certain point in time and can look up when required?

One more, 666 is the sum of the first 144 decimals of π.

I am curious about can we solve the problem C by using C++ sort() and passing a comparator function? And then checking whether it's sorted or not.

B: Without permutation or graphs

1. Rearrange the equations such that all inequalities face LHS i.e, x > y
2. If the number of unique characters in LHS and RHS != 2, the solution does not exist.
3. The character with frequency 2 on LHS is maximum and one with frequency 2 on RHS is minimum.

Please don't spam Codeforces at least. There are many who don't know the context and it gets annoying after a while.

Excuse my ignorance, but what is the rule exactly you're talking about?
