Solution
Sure, here is a Python program that calculates the Hailstone sequence:
def hailstone(n):
sequence = [n]
while n != 1:
if n % 2 == 0:
n = n // 2
else:
n = 3 * n + 1
sequence.append(n)
return sequence
n = int(input("Enter a number: "))
sequence = hailstone(n)
print(" ".join(str(i) for i in sequence))
print("The length of the sequence is {}.".format(len(sequence)))
This program defines a function hailstone that takes an integer n as input and generates the Hailstone sequence starting from n. The sequence is stored in a list. The function uses a while loop to generate the sequence: if n is even, it is divided by 2; if n is odd, it is multiplied by 3 and 1 is added. The new value of n is appended to the list. The loop continues until n is 1.
The program then asks the user to input a number, generates the Hailstone sequence for that number, and prints the sequence and its length.
