Find Lettergrade, using Searched Case SQL assignement.

We made a program earlier to find a Lettergrade $($A$,$B$,$C $...)$ based on test Score by using IF$...$ELSIF $...$ELSIF $...$END IF;

Now, please re$-$do same program and logic by using "Searched Case" instead of $"$If$"$ statements. Searched Case is the one that does not have a variable right after CASE on the first line of it$,$ but instead have conditions similar to IF $...$ ELSIF, but under each WHEN.

Please enter test Score from keyboard, then the program should display corresponding letter grade with a comment about the grade.

Use a CASE Expression in your SQL program.
