Write a program that accept marks in 4 subjects, the program then compute and output total, average, and grade and remark based on the following grading system. a) Use if else b) Use switch case Marks Grade Remark 70-100 A Excellent 60-69 B Good 50-59 C Satisfactory 40-49 D Pass 0-39 F Fail

# Program using if-else
def calculate_grade(marks):
    total = sum(marks)
    average = total / len(marks)
    
    if average >= 70:
        grade = 'A'
        remark = 'Excellent'
    elif average >= 60:
        grade = 'B'
        remark = 'Good'
    elif average >= 50:
        grade = 'C'
        remark = 'Satisfactory'
    elif average >= 40:
        grade = 'D'
        remark = 'Pass'
    else:
        grade = 'F'
        remark = 'Fail'
    
    return total, average, grade, remark

marks = [float(input("Enter marks for subject {}: ".format(i+1))) for i in range(4)]
total, average, grade, remark = calculate_grade(marks)
print(f"Total: {total}, Average: {average}, Grade: {grade}, Remark: {remark}")
