I saw this solution of a 7* coder from japan
and this code of a 6* coder from india
Since both of them use the exact same class LST. I am assuming its something very common. But i dont undrerstand the code its too high level for me. I already have solution ready that uses red-black trees. I am going through the codes of the best programmers out there so that i may learn something new. Can anyone please help me out?
