PROGRAMMING:Calculate the score

Xiaolang is a member of the class's Sports Committee. When the PE exam is over, the PE teacher shouts Xiaolang to help the teacher calculate the sit up scores. The calculation rules are as follows:
45 passed, 60 points. 62 good, 70 points. 70 excellent, 90 points[ 45,62) plus 0.5 points for each[ 62, 70) plus 1.25 points for each; Add 2 points for each score above 70 points (including 70 points);
For less than 45 points, in order to ensure the overall score is not too low, the number of points below 45 is + 10 points. The score can not exceed 100, that is, if it exceeds 100, the score will be calculated as 100.
The question guarantees that the test data does not appear negative, and the minimum is 1.
