$($Making Groups$)$ Each week, your Computer Science class splits into groups of $4$ for activities.

However, to prevent the same groups from forming every week, the instructor devised the

following strategy for creating groups randomly:

Each student draws a number between $1$ and $4$ from a hat.

Each student goes to one of four lines, corresponding to the number they drew.

Once all numbers have been drawn, each group is formed by taking the first student

from lines $1$ and $3,$ and the last student from lines $2$ and $4.$

Whenever a student is added to a group, they are removed from their line.

Your job is to write a program that takes a list of students and the number they drew as input, and

outputs the resulting groups.

Input Format:

Input starts with a single integer $N,$ which specifies the number of students to follow. The following

$N$ lines of input each contain a student's name as well as the number they drew.

Take the following input as an example:

$8$

Quinton $3$

Zoey $1$

Graham $1$

Justice $4$

Ruby $2$

Greg $4$

Lamar $3$

Steven $2$

The first line $"8"$ indicates that there are eight students in the class. The following eight lines

specify the name of the student and the number they drew. Quinton drew the number $3,$ Zoey

drew the number $1,$ Graham drew the number $1,$ and so on$.$

Note: There will always be enough students to form groups of $4$ without having any left over.

Output

Print each group that was generated from the input to the console. Groups should be printed in

ascending order, and each student within the group should be in ascending order based on the

number they drew

Note: In this question, you are required to utilize the StringLinkedList class as a library. This

means you must modify the IntLinkedList class library according to the requirements of this

question.
