Programming Task 1: Happy Number A happy number is a number defined by the following process: Starting with any positive integer, replace the number with the sum of the squares of its digits. Repeat the process until the number equals 1 (where it will stay), or it loops endlessly in a cycle which does not include 1. Those numbers for which this process ends in 1 are happy. Example: 13 is a happy number. Input: number 13 12132-19-10 1²+0²-1 11 is an unhappy number. Input: number -11 1²+1²-11-2 2²-4 4² = 16 12+6²-1+36-37 32+72 9+49-58 5²1 82 25 1 64-89 82 +92-64 +81-145 1² +42 +5²-1-16-25-42 4²22-16+4-20 22 +0²=4+0-4 (Endless Loop) Write a program in Java that prints Happy, if the input number is happy otherwise print unhappy. . Input: 7 Output: happy Java • Input: 26 Output: Unhappy Happy Numbers: 1, 7, 13, 28, 32 etc. Unhappy Numbers: 4, 9, 11, 26, 38 etc. Note: You are not allowed to use sets or hashset as we have not covered that in our syllabus.
