p03251 AtCoder Beginner Contest 110 - 1 Dimensional World's Tale
Our world is one-dimensional, and ruled by two empires called Empire A and Empire B.

The capital of Empire A is located at coordinate X, and that of Empire B is located at coordinate Y.

One day, Empire A becomes inclined to put the cities at coordinates x_1, x_2, ..., x_N under its control, and Empire B becomes inclined to put the cities at coordinates y_1, y_2, ..., y_M under its control.

If there exists an integer Z that satisfies all of the following three conditions, they will come to an agreement, but otherwise war will break out.

* X < Z \leq Y
* x_1, x_2, ..., x_N < Z
* y_1, y_2, ..., y_M \geq Z



Determine if war will break out.

Constraints

* All values in input are integers.
* 1 \leq N, M \leq 100
* -100 \leq X < Y \leq 100
* -100 \leq x_i, y_i \leq 100
* x_1, x_2, ..., x_N \neq X
* x_i are all different.
* y_1, y_2, ..., y_M \neq Y
* y_i are all different.

Input

Input is given from Standard Input in the following format:


N M X Y
x_1 x_2 ... x_N
y_1 y_2 ... y_M


Output

If war will break out, print `War`; otherwise, print `No War`.

```python
N,M,X,Y=map(int,input().split())
x=list(map(int,input().split()))
y=list(map(int,input().split()))
if max(max(x),X)<min(min(y),Y):
    print('No War')
else:
    print("War")
