As an example, consider the following file: 5 2016ucs0003 D 2016ucs0001 B 2016ucs0002 A- 2016ucs0005 B 2016ucs0007 B 2016ucs0008 A Write a program to read the grades from the file (assume file name is grades.txt) Print the no. of students for each grade sorted by the number of students. For example, for the file given above, the output would be: В З А 1 A- 1 D 1 В- 0 со ? C- 0 F 0 LIVE EVENTS R 11:48 hackerearth.com/challe 3 y the TTuMiber UT StudeTTts. TorExampie, the file given above, the output would be: В З 5 А 1 A- 1 D 1 В- О со C- 0 Е О FO Notice that "B 3" is printed first because it has the maximum no. of students(3). Similarly, "D 1" is printed before "B- 0" If two grades have the same no. of students, you can print them in any order. In the example above, the higher grade is printed first, but doing that is optional. The domain of the grade values is all the grades supported by the IT Jammu system: A, А-, В, В-, С, С-, D, E, F. ?
