Question

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)

Answer 1

To determine if a number is a happy number, you would typically use a **while loop**. This is because you need to repeatedly calculate the sum of the squares of the digits of the number until you either reach 1 (indicating that it is a happy number) or enter a cycle that leads to 4 (indicating that it is an unhappy number).

Using a while loop allows you to continue this process until one of the two conditions is met.

Thus, the correct response is:

**while loop**
