A happy number is a number which yields a 1 by repeatedly summing up the square of its digits. If such a process results in an endless cycle of numbers containing 4, the number is said to be an unhappy number. Create a function that accepts a number and determines whether the number is a happy number or not. Return true if so, false otherwise. Examples isHappy (67) false isHappy (89) → false isHappy (139) - true
