PROGRAMMING:Score of singing competition
There are 10 singers (numbered 1-10) participating in the singing competition, and another 6 judges scoring. The score of each singer is input from the keyboard to calculate the final score of each singer (the average score after deducting the highest score and the lowest score). Finally, the number and final score of each singer are output in the order of final score from high to low.
###Input format:
Enter the score of the first singer's 6 judges in turn (10 point system, the score is integer, and the scores are separated by spaces), the score of the second singer's 6 judges... And so on.
###Output format:
Refer to the output example, output the number and final score of each singer in the order of final score from high to low (the final score retains 2 decimal places).
###Input example:
