Top Student Selection

You are given several test cases. Each test case contains details of students along with their marks in two subjects: Mathematics and Science. Your task is to determine the top student for each test case based on the following criteria:

1. The student with the highest aggregate score is the top student. The aggregate score is calculated as $$\text{Mathematics}+\text{Science}$$.
2. If there is a tie in aggregate scores, the student with the higher Mathematics score is selected.
3. If there is still a tie, choose the student whose name comes first in lexicographical order.

Note that student names are case-sensitive and do not contain spaces.

inputFormat

The input is given from standard input and consists of multiple lines:

• The first line contains an integer $$T$$, the number of test cases.
• For each test case, the first line contains an integer $$N$$, the number of students.
• This is followed by $$N$$ lines, each containing a student's information in the format: Name Mathematics Science, separated by spaces.

outputFormat

For each test case, output the name of the top student on a new line to standard output.## sample
