##### Recipe 5

Calvin has recently programmed a game and wants you to beta test it for him. In this game, you are playing as an burglaradventurer

in a world of towns (numbered from to ) and unidirectional roads that run between them. In each of these towns, there is a bank you can pillageborrow

stuff from, and coins can be borrowed from each bank . Your job is to try and borrow as many coins as possible! You may visit towns as many times as you want, but the bank does not refill after you raidtake a loan from

them.

In addition, we know there are a certain number of provinces in this world. A province is defined as a maximal group of cities in which you can travel from any city in the group to any other city in the group by following some roads. Calvin has made this game more fun by programming an policeanti-borrow

system. You CANNOT borrow from two consecutive provinces on your path as men in black suits will show up and confiscate your loot. Being allergic to losing, you would like to find the maximum number of coins you can borrow in one run of this game from town to town , and the number of distinct paths you can take to do this. A distinct path is defined as a path **of provinces** that either goes to provinces in a different order, visits a different set of provinces, or borrows from a different set of provinces. More formally, two paths and consisting of a set of provinces are considered distinct only if or for any . Since there may be many ways, output the number of ways modulo .

#### Input Specification

Line 1: 2 integers, space separated — and

Next line: space separated integers, the integer is the amount of loot you can hoard from town ,

Next lines: 2 integers, space separated — and . Each pair indicates a unidirectional path from town to town . There may be self-loops and duplicate edges.

#### Output Specification

One line with two integers space separated, the maximum amount you can borrow and the number of ways there are to do this. It is guaranteed that there is at least one way to borrow from town to town .

#### Sample Input

```
6 7
1 1 1 1 1 1
1 2
2 3
3 1
4 5
5 6
6 4
3 4
```

#### Sample Output

`3 2`

#### Explanation of Output for Sample Input

The towns are arranged as shown above, and each town can be looted for 1 unit of money. The sets of towns and are the provinces, since every town leads to every other town in each set. You want to get from town 1 to 6, and cannot visit both provinces since they are connected with a path, or else you will get beat up. Therefore, the best paths to take is travelling through all the towns,either looting all banks in province , or looting all banks in the province . After doing this, you can take the remaining paths to arrive at town 6.

I'm done with this: When test case 7 ACed, test case 9 TLEd; When test case 9 ACed, test case 7 TLEd.

Hey admins,

The best submission for ZGW1512 or whatever his handle is has one WA but shows up as 25/25 points AC. Here it is.

The submission has been rejudged.

Haha, how did that even happen? Any ideas?

Choosing the same set of provinces but pillaging from different provinces also counts as a distinct path.

For the input

the answer should be

Awaiting more clarification from the authors.
