Beijing Institute of Technology on a machine problem - Student Information System
Subject description:
the establishment of a student information system, student information input and output information hanging branches of the students, then the average score highest to lowest output
Input:
aaa 70 80 90
bbb 65 32 77
ccc 100 55 68
ddd 86 77 90
eee 1,005,966
output:
* [BBB] 65 32 77
* [CCC] 55 100 68
* [Eee] 1005966
ddd 86 77 90
AAA 70 80 90
Eee 1,005,966
CCC 100 55 68
BBB 65 32 77
