Write a program, enter the percentile score (non-negative integer), and convert it to a 5-point score. The relationship between the scores is as follows:
90-100： 5
80-89： 4
70-79: 3
60-69: 2
10-59: 1
0-9： 0
Input: non-negative integer
Output: an integer between [0,5]
Sample 1 input:
80
Sample 1 output:
4
Note: Please use if...else if...else... and switch to achieve.
