Suppose the grading system in a University is A: $4\mathrm{.}0,$ A$-$: $3\mathrm{.}7,$ B$+$: $3\mathrm{.}3,$ B: $3\mathrm{.}0,$ B$-$: $2\mathrm{.}7,$ C$+$: $2\mathrm{.}3,$ C: $2\mathrm{.}0,$ D: $1\mathrm{.}0$ and F: $0\mathrm{.}0.$ Write an algorithm and draw a flowchart to calculate the G P A o f a s t u d e n t b a s e d o n t h e i r g r a d e s in $5$ c o u r s e s $.$GPA $=$ total grade points $/$ total coursesLet's assume the student received the following grades: C o u r s e $1$: A C o u r s e $2$ : B$+$ Course $3$: C Course $4$: A$-$ Course $5$: BInputs will be in letter grade. Convert them within your algorithm$/$flowchart$.$
