##### DWITE, October 2012, Problem 4

You just moved into a strange neighbourhood. You notice that the roads in your neighbourhood form a binary tree, with the houses forming the leaves of the tree. But this doesn't really matter to you, because it's all about the candy during Halloween! However having just moved in, you might end up getting lost. So you create a plan: start at the root of your neighbourhood and walk to every house and ask for candy! Before setting off on your adventure however, you want to calculate the minimum number of roads you'll need to walk and the total amount of candy you'll get.

The input will contain 5 test cases. Each test case is a line containing a single string, less than 256 characters long, describing the tree your neighbourhood forms. A binary tree can be recursively described as either:

- A leaf , , the amount of candy received from the house
- - where represents a tree

For example, a tree represented by would look like:

The output will contain 5 lines of output, each a pair of integers and . is the minimum number of roads needed to be traversed to get all the candy (starting from the root (top) of the tree, and not needing to return). represents the total amount of candy you'll collect.

#### Sample Input

```
((1 5) 8)
(1 3)
```

#### Sample Output

```
6 14
3 4
```
