Only solutions using awk will be considered valid for this task

You are provided a file with four space-separated columns containing the scores of students in three subjects. The first column, contains a single character (A-Z) - the identifier of the student. The next three columns have three numbers (each between 0 and 100, both inclusive) which are the scores of the students in English, Mathematics and Science respectively.

> Input Format

There will be no more than 10 rows of data. Each line will be in the format:

[Identifier]<space>[Score in English]<space>[Score in Math]<space>[Score in Science]

> Output Format

Concatenate every 2 lines of input with a semi-colon.

> Sample Input

A 25 27 50
B 35 37 75
C 75 78 80
D 99 88 76
