PROGRAMMING:Statistics of a group of students' average score and the number of failed students
This problem requires the preparation of procedures to calculate the average score of students, and statistics of the number of students who fail (the score is less than 60). Ensure that the input and output are within the double precision range.
###Input format:
Input gives a series of nonnegative real numbers on a line, separated by spaces. When a negative real number is read, it means the end of input, and the number should not be processed.
###Output format:
Output in the following format:
```
Average = average score
Count = number of failed students
```
The average value is accurate to two decimal places, and there is a space around the equal sign.
###Input sample 1:
```in
67 88 73 54 95 60 0 -1
```
###Output sample 1:
```out
Average = 62.43
Count = 2
```
###Input sample 2:
```in
-100 90 80 0
```
###Output sample 2:
```out
Average = 0.00
```
