In order to improve your CGPA calculation, you will implement Dalhousie's grade replacement rule to the work that you did in Problem 2 If a course is repeated, the initial attempt is not included in the CGPA. For example, if you get a B in a course that you had previously failed, only the B is included in your CGPA. For the sake of this exercise, the GPA for the previous semester is not affected.[1] Input (Same as Problem 2] Processing 1. Convert each letter grade to the appropriate grade point value Disregard any neutral grade letters (e.g. W or ILL grades) 2 Calculate the GPA and CGPA at the end of each semester and output semester information If any course is repeated, make sure to disregard/overwrite the first attempt when calculating the CGPA (as described above) Sample Input Sample output 3 SEMESTERS 6 CLASSES Transfer Credits ENGI 1123,B MATH 1000,F Summer 2018 SEMESTER: Transfer Credits GPA: 1.5 CGPA: 3.0 SEMESTER: Summer 2018 GPA: 20 CGPA: 3.5 SEMESTER: Fall 2018 GPA: 3.5 CGPA: 3.5 CSCI 1110,F MATH 1000,A Fall 2018 MATH 1010,B CSCI 1110,A 2 SEMESTERS 11 CLASSES Summer 2018 SEMESTER: Summer 2018 GPA: 1.75 CGPA: 3.0 SEMESTER: Fall 2018 GPA: 268 CGPA: 2.77 CSCI 1107,ILL CSCI 1120,F CSCI 1110.D CSCI 1800,C+ MATH 1000, A- Fall 2018 MATH 1010,B- CSCI 1110,C CSCI 1120,B CSCI 1170,C- CSCI 1108, A PSYC 1201,W 2 SEMESTERS 13 CLASSES Fall 2018 SEMESTER: Fall 2018 GPA: 206 CGPA: 3.1 SEMESTER: Winter 2018 GPA: 3.27 CGPA: 3.21 CSCI 1107,ILL CSCI 1120,F CSCI 1110,D CSCI 1800,C+ MATH 1000, A- MATH 2112,B+ Winter 2018 MATH 1010, A- CSCI 1110,B+ CSCI 1120,C+ CSCI 1801,A+ CSCI 2110,W CSCI 1170,C- CSCI 1108, A+ [1] In reality, the GPA is updated such that a replaced grade is no longer included for the semester affected, as if it had never happened
