The happy number can be defined as a number which returns 1 when replaced by the sum of the square of each digit. For instance, 13 is a happy number because 12+32=10→12+02=1

. Number 32 is a happy number because 32+22=13→12+32=10→12+02=1
. Other examples of happy numbers are 7, 28, 100, 320. A number is unhappy if the process yields a 4. Which of the following constructs would we need to find out if a number is happy?(1 point)

To determine if a number is a happy number by repeatedly replacing it with the sum of the squares of its digits until it reaches 1 or falls into a cycle (which would indicate it is unhappy), you would typically use a while loop.

This is because you want to keep iterating over the process of computing the sum of the squares of the digits until you reach a termination condition (either reaching 1 or detecting that you've entered a cycle).

Therefore, the correct choice would be:

while loop
