题目描述

Jellyfish loves playing a game called "Inscryption" which is played on a directed acyclic graph with nn vertices and mm edges. All edges aba \to b satisfy a<ba < b .

You need to move from vertex 11 to vertex nn along the directed edges, and then fight with the final boss.

You will collect cards and props in the process.

Each card has two attributes: HP and damage. If a card's HP is aa and its damage is bb , then the power of the card is a×ba \times b .

Each prop has only one attribute: power.

In addition to vertex 11 and vertex nn , there are some vertices that trigger special events. The special events are:

  1. You will get a card with aa HP, and bb damage.
  2. If you have at least one card, choose one of your cards and increase its HP by xx .
  3. If you have at least one card, choose one of your cards and increase its damage by yy .
  4. You will get a prop with ww power.

When you get to vertex nn , you can choose at most one of your cards and multiply its damage by 10910^9 .

The final boss is very strong, so you want to maximize the sum of the power of all your cards and props. Find the maximum possible sum of power of all your cards and props if you play the game optimally.

输入格式

The first line contains two integers nn and mm ( 2n2002 \leq n \leq 200 , n1mmin(n(n1)2,2000)n - 1\leq m \leq \min(\frac{n(n-1)}2, 2000) ) — the number of the vertices and the number of the edges.

In the following nn lines, the ii -th (1in)(1 \leq i \leq n) line describes the special event that will trigger on vertex ii :

  • 0 — no special events.
  • 1 a b ( 1a,b2001 \leq a, b \leq 200 ) — you will get a card with aa HP, and bb damage.
  • 2 x ( 1x2001 \leq x \leq 200 ) — if you have at least one card, choose one of your cards and increase its HP by xx .
  • 3 y ( 1y2001 \leq y \leq 200 ) — if you have at least one card, choose one of your cards and increase its damage by yy .
  • 4 w ( 1w1061 \leq w \leq 10^6 ) — you will get a prop with ww power.

In the following mm lines, each line contains two integers uu and vv ( 1u<vn1 \leq u < v \leq n ) representing a directed edge from vertex uu to vertex vv .

It is guaranteed that every edge (u,v)(u,v) appears at most once.

It is guaranteed that there are no special events on vertex 11 and vertex nn .

It is guaranteed that for all ii , there exists a path from vertex 11 to vertex nn that passes through vertex ii .

输出格式

Output a single integer — the maximum sum of the power of all your cards and props.

说明/提示

In the first example, we will play the game in the following order:

  • move from vertex 11 to vertex 22 , get a card with 22 HP, and 1010 damage.
  • move from vertex 22 to vertex 44 , choose the card we get from vertex 22 and increase its HP by 88 .
  • move from vertex 44 to vertex 66 , choose the card we get from vertex 22 and multiply its damage by 10910^9 .

In the end, we will have a card with (2+8)=10(2+8)=10 HP and 10×109=101010 \times 10^9=10^{10} damage, It's power is 10×1010=101110 \times 10^{10}=10^{11} . Because we only have the card we get from vertex 22 , so the sum of power of all your cards and props is 101110^{11} .
