+Step 1: Prompt the user to enter numberOfStudents (int).
+
+Step 2: Create an array for scores using new double[numberOfStudents].
+
+Step 3: Declare and initialize variable best to keep the best score.
+Set the initial value to 0.
+
+Step 4: Prompt the user to enter the scores in a loop that executes 
+numberOfStudents times. 
+For each score entered, store it in scores[i]. 
+Compare it with best. If it is greater than best, assign it to best.
+
+Step 5: Write a for loop for i from 0 to numberOfStudents - 1, 
+compare scores[i] with grade to assign the grade for the student.
