Topper of the class

Problem

Marks arrive as CSV lines. Print the name of the student with the highest mark. If two students tie, print the one who appears first.

Example

Input

3
Asha,82
Ravi,91
Meena,91

Output

Ravi

Ravi and Meena tie; Ravi comes first.

Try the problem first. Open one hint at a time.

Hint 1

Convert the mark to an int, not text, or "9" would beat "85".

Hint 2

max returns the first of equal items when you give it a key.

Write your Python code, run it on the examples and submit it to hidden tests.
