Write a program that will read data from the file "p6.txt". The file (that you will create) always contains 15 test scores (whole numbers between 0 and 100). The test scores are scores for 5 students taking 3 tests, and are arranged, in the file, by the student - that is the first 3 numbers are the test scores for test 1, 2, and 3 for the first student, etc.
The program will print:

1. - average per student (5 averages), on a single line, with 2 decimals
2. - average per test (3 averages), on a single line, with 2 decimals
3. - overall best score on a single line
4. - HOW MANY SCORES WERE Fs(out of the 15, how many were at most 59) on a single line

To simplify the code, no validations are needed. That is, assume the file is successfully opened, and that all data are 0-100, and that there are exactly 15 numbers in the file.
