# 1028 List Sorting (PTA)

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 (≤10​5​​) and C, where N is the number of records and C is 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).

### 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

records.sort(key=lambda x: (x[ref - 1],x[0]))
for i in records:
