PROGRAMMING:Statistical score 1
Given the basic information of n students, including student number (a string composed of 12 digits), name (a non empty string less than 20 in length that does not contain white space characters), higher mathematics scores, C language programming scores, the scores are all integers in the [0100] range, it is required to count the number of students who fail in higher mathematics, According to the input order, the list of students who failed in higher mathematics is given.
###Input format:
The input gives a positive integer n (≤ 10) on one line.
Then n lines, each line gives a student's information, the format is "student number name advanced mathematics score C language programming score", separated by a space.
###Output format:
First, output the number of students who failed in advanced mathematics in one line, and then output the student number and name of a student who failed in this score in each line according to the input order, with a space between them.
###Input example:
```in
three
201410300106 wanyun 70 88
201618050322 zhangyu 59 60
201509210118 lixiao 80 80
```
###Output example:
```out
one
201618050322 zhangyu
