Enter the student numbers of one class 10 and the scores of three subjects (mathematics, English and computer basics) of each student. The program calculates the total score and average score of each student, sorts them according to their grades, and finally prints out the report cards sorted from high score to low score. Requirements:
1) sorting is realized by a function.
2) The printed report card items include: serial number, student number, mathematics, English, computer, total score and average score.
3) Fill in the experimental contents according to the electronic template format of the experimental report.
