Assuming that the basic information of students includes student number, name, three course scores and personal average score, a structure type that can represent the information of students is defined. Input the score information of n (1 < = n < = 10) students, calculate and output the student with the highest average score, and keep the average score to two decimal places. If there are more than one student with the highest average score, output the information of the first student in the order of input.
###Input format:
Enter the integer n (1 < = n < = 10), and enter the information of n students in the following N lines, including student number, name and three course scores (integer).
###Output format:
Output the student information with the highest average score in one line: student number, name and average score (with two decimal places reserved).
