一些自己用的输入输出语句。

<!-- more -->

## Python 输入

### 输入一行由空格切分的值

```python
# py2
w = raw_input().split()
# py3
w = input().split()
```

### 输入整形变量

```python
# py2
w = map(int,raw_input().split())
# py3
w = map(int,input().split())
```

## JAVA 中在 OJ 上怎么实现多组输入

```java
import java.util.Scanner;

public class Main {
	public static void main(String[] args) {
		Scanner sc = new Scanner(System.in);
        while(sc.hasNext()) {
    		double a = sc.nextDouble();
			// DO
        }
	}
}
```

## C 多组输入

```c
int a, b;
while(scanf("%d%d", &a, &b) != EOF)
{
}
```

## C++中在 OJ 上怎么实现多组输入

```cpp
while(cin >> a >> b){
}
```
