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

# Function to calculate total, average, grade, and remark using if-else
def calculate_grade_if_else(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

# Input marks
marks = [float(input(f"Enter marks for subject {i+1}: ")) for i in range(4)]
total, average, grade, remark = calculate_grade_if_else(marks)

# Output results
print(f"Total: {total}, Average: {average}, Grade: {grade}, Remark: {remark}")

# Function to calculate total, average, grade, and remark using a simulated switch case
def calculate_grade_switch_case(marks):
    total = sum(marks)
    average = total / len(marks)

    # Simulating switch case using a dictionary
    switch = {
        (average >= 70): ('A', 'Excellent'),
        (average >= 60): ('B', 'Good'),
        (average >= 50): ('C', 'Satisfactory'),
        (average >= 40): ('D', 'Pass'),
    }
    
    grade, remark = next((value for key, value in switch.items() if key), ('F', 'Fail'))
    
    return total, average, grade, remark

# Input marks
