T1 Merchant

 


 

Since each set can be written in a form of a function, it is assumed that L is a monotonic function, the better the greater as the t

And monotonically decreasing function of t is increased with the result of smaller, so it is not monotonous? ? ?

But just by virtue of our monotonous sum is greater than the value at time t to S

If a single down a set of compliance, then he at t 0 == time to time compliance

If not, then he would not contribute

So can bipartite

 

T2 Equation


 

I thought it was a Gaussian elimination? ? ?

of course not.....

The xi are each represented by x1, we found that for different depths parity point, his representation is different, two statistics on the line,

Query is O (1), and in some cases just minutes

Modifications, can be considered a tree maintenance difference array, difference is in the DFS sequence at the L -, R + at the last maintenance suffix,

Fenwick tree will be two cards, it is indicated with a point of singularity, even the opposite of that number.
