题目描述

Phoenix wonders what it is like to rob diamonds from a jewelry store!

There are nn types of diamonds. The ii -th type has weight wiw_i and value viv_i . The store initially has aia_i diamonds of the ii -th type.

Each day, for qq days, one of the following will happen:

  1. A new shipment of kik_i diamonds of type did_i arrive.
  2. The store sells kik_i diamonds of type did_i .
  3. Phoenix wonders what will happen if he robs the store using a bag that can fit diamonds with total weight not exceeding cic_i . If he greedily takes diamonds of the largest value that fit, how much value would be taken? If there are multiple diamonds with the largest value, he will take the one with minimum weight. If, of the diamonds with the largest value, there are multiple with the same minimum weight, he will take any of them.

Of course, since Phoenix is a law-abiding citizen, this is all a thought experiment and he never actually robs any diamonds from the store. This means that queries of type 33 do not affect the diamonds in the store.

输入格式

The first line contains two integers nn and qq ( 1n21051 \le n \le 2 \cdot 10^5 ; 1q1051 \le q \le 10^5 ) — the number of types of diamonds and number of days, respectively.

The next nn lines describe each type of diamond. The ii -th line will contain three integers aia_i , wiw_i , and viv_i ( 0ai1050 \le a_i \le 10^5 ; 1wi,vi1051 \le w_i, v_i \le 10^5 ) — the initial number of diamonds of the ii -th type, the weight of diamonds of the ii -th type, and the value of diamonds of the ii -th type, respectively.

The next qq lines contain the queries. For each query, the first integer of each line is tt ( 1t31 \le t \le 3 ) — the type of query.

If t=1t=1 , then two integers kik_i , did_i follow ( 1ki1051 \le k_i \le 10^5 ; 1din1 \le d_i \le n ). This means that a new shipment of kik_i diamonds arrived, each of type did_i .

If t=2t=2 , then two integers kik_i , did_i follow ( 1ki1051 \le k_i \le 10^5 ; 1din1 \le d_i \le n ). This means that the store has sold kik_i diamonds, each of type did_i . It is guaranteed that the store had the diamonds before they sold them.

If t=3t=3 , an integer cic_i will follow ( 1ci10181 \le c_i \le 10^{18} ) — the weight capacity of Phoenix's bag.

It is guaranteed that there is at least one query where t=3t=3 .

输出格式

Print the answer for each query of the third type ( t=3t=3 ).

说明/提示

For the first query where t=3t=3 , Phoenix can fit 22 diamonds of type 11 , with total weight 66 and value 88 .

For the second query where t=3t=3 , Phoenix will first fit in 33 diamonds of type 33 , then one diamond of type 11 for a total weight of 99 and a value of 1616 . Note that diamonds of type 33 are prioritized over type 11 because type 33 has equal value but less weight.

For the final query where t=3t=3 , Phoenix can fit every diamond for a total value of 1313 .
