Question 06:
Write a Python program to find the largest among three numbers.

Answer:
def main(numbers: list[int]) -> None:
    if not numbers:
        print("No numbers provided.")
        return
    
    largest = numbers[0]
    for num in numbers:
        if num > largest:
            largest = num
            
    print("Largest number:", largest)

if __name__ == '__main__':
    main([1, 2, 3])
    main([3, 1, 2])
    main([5, 10, 15, 20])


Output:
Largest number: 3
Largest number: 3
Largest number: 20
