Returns
1004 scores ranking (20 point (s))
Read in n (& gt; 0) student name, student id, achievements, respectively, the highest output performance and lowest student name and student id,

Input format:
Each test input contains one test case, the format for

Line 1: the positive integer n
Line 2: a student's name and student id 1 score
Line 3: the second student name and student id scores
. . .
N + 1: n a student's name and student id result



Including name and student number are a string of not more than 10 characters, performance for an integer between 0 and 100, this guarantee in a set of test cases that no two student's result is the same,

The output format:
For each test case output line 2, line 1 is the top student name and student number, line 2 will be the lowest grade student's name and student id, one space between strings,

C language does not support this definition, an array must be given a constant value

For your reference ~

C language does not support variable-length arrays, in addition, the name, code for the test cases, already crossed, so suggest to increase the length of the array (name, code)
