17657번 - Seats 서브태스크다국어

The subway in town X is a bit unusual. One train consists of a single wagon and there is a single row of L seats in it. If there are N passengers in the wagon, numbered from 0 to N-1, each passenger gets a certain amount of pleasure as follows:

• If a passenger is standing, he gets pleasure equal to 0;
• Otherwise the passenger gets A[i] pleasure from sitting and additional B[i] pleasure for each empty seat between him and a neighboring passenger or between him and the end of the seats row.

For example let’s have 3 passengers in the wagon, numbered 0, 1 and 2, and A[0]=5, B[0]=2, A[1]=10, B[1]=1, A[2]=1, B[2]=1. Let the number of seats L=6 and consider the passengers sitting in the following schema: _ 0 _ _ 1 _ (“_” means an empty seat)

Passenger 2 is standing.

In this case:

• Passenger 0 gets pleasure 5, because he is sitting + pleasure 6, because of the empty seats (1 to the left and 2 to the right). That’s a total pleasure of 11.
• Passenger 1 gets pleasure 10, because he is sitting + pleasure 3, because of the empty seats (2 to the left and 1 to the right). Total of 13.
• Passenger 2 gets pleasure 0, because he is standing.

The total pleasure of all the passengers is equal to 24.

Write program, which, given the number of seats L, the number of passengers N and the pleasure characteristics for each passenger, determines the maximum possible total pleasure for any number of seated passengers between 1 and N.

The first line of the standard input contains two integers – N and L - the number of passengers and the number of seats.

Each of the next N lines contains two non-negative integers – the characteristics А[i] and B[i] for passenger with index i.

Print N lines, the K-th of which contains a single number – the maximum total pleasure that the passengers can get if there are exactly K of them sitting.

(For K > L print 0, because there are no valid configurations of K passengers on L seats )

• 1 ≤ N ≤ 100 000
• 1 ≤ L ≤ 200 000
• 0 < A[i], B[i] < 10⁹
