Dmojistan has declared war on Pegland! Both countries have sent a missile towards each other, but due to a miscalculation, the missiles are going to collide mid-flight. The missiles are traveling over neutral Wlmojistan, and they are going to unleash terrors like internal errors, TLEs and undefined behaviours. Thankfully, MCPT, the Missile Collision Prevention Team has a device that can neutralize both missiles if provided their collision point. Given the coordinates of the starting and ending position of both missiles, determine the collision point of the missiles.

#### Input Specification

The first line of input contains four integers, , , , and , the starting and ending coordinates of the first missile.

The second line of input contains four integers, , , , and , the starting and ending coordinates of the second missile.

#### Output Specification

Output the coordinate of the collision point of the two missiles. Round values to 1 decimal place.

#### Constraints

#### Sample Input

```
0 3 4 5
0 10 3 1
```

#### Sample Output

`2.0 4.0`
