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) Responses for loop for loop list list queue queue while loop

Answer 1

The correct answer would be a while loop.

A while loop allows us to repeatedly perform a set of instructions as long as a certain condition is true. In this case, we can use a while loop to repeatedly calculate the sum of the squares of the digits of the number until we either reach 1 (which would make it a happy number) or 4 (which would make it an unhappy number).
