1. if a student 'A' has lower marks in physics than a student 'B', then A's data is listed before B.
2. If A and B have the same physics marks and A has lower chemistry marks than B, then A is listed before B. 3.If A and B have the same marks in physics and chemistry, and A has lower marks in mathematics than B, then A is listed before B.
3. If all marks are equal and A's name precedes B's name in the dictionary order, then A is listed before B.

Input Format :

First line contains the number of students n, where 1<=n<=100. In following n lines each line contains(space separated) a name and their respective marks in physics, chemistry, maths, where 0<=marks<=100.
