Source: [PAT 1028]

### Description #

Excel can sort records according to any column. Now you are supposed to imitate this function.

Input Specification: Each input file contains one test case. For each case, the first line contains two integers `N(≤105)`

and `C`

, where `N`

is the number of records andCis the column that you are supposed to sort the records with. Then `N`

lines follow, each contains a record of a student. A student’s record consists of his or her distinct ID (a 6-digit number), name (a string with no more than 8 characters without space), and grade (an integer between 0 and 100, inclusive).

### Input Specification #

For each test case, output the sorting result in `N`

lines. That is, if `C = 1`

then the records must be sorted in increasing order according to ID’s; if `C = 2`

then the records must be sorted in non-decreasing order according to names; and if `C = 3`

then the records must be sorted in non-decreasing order according to grades. If there are several students who have the same name or grade, they must be sorted according to their ID’s in increasing order.

### Output Specification #

For each test case, output the sorting result in `N`

lines. That is, if `C = 1`

then the records must be sorted in increasing order according to ID’s; if `C = 2`

then the records must be sorted in non-decreasing order according to names; and if `C = 3`

then the records must be sorted in non-decreasing order according to grades. If there are several students who have the same name or grade, they must be sorted according to their ID’s in increasing order.

### Sample Input 1: #

```
3 1
000007 James 85
000010 Amy 90
000001 Zoe 60
```

#### Sample Output 1: #

```
000001 Zoe 60
000007 James 85
000010 Amy 90
```

#### Sample Input 2: #

```
4 2
000007 James 85
000010 Amy 90
000001 Zoe 60
000002 James 98
```

#### Sample Output 2: #

```
000010 Amy 90
000002 James 98
000007 James 85
000001 Zoe 60
```

#### Sample Input 3: #

```
4 3
000007 James 85
000010 Amy 90
000001 Zoe 60
000002 James 90
```

#### Sample Output 3: #

```
000001 Zoe 60
000007 James 85
000002 James 90
000010 Amy 90
```

## Solution #

解法： 1.读入所有数据 2.根据c调用不同的排序方法 3.打印
