To determine if 2 is a happy number or unhappy number, we square each digit in 2 and then add those numbers together.
Then we repeat the process for the result until either the result turns to 1 or we realize it will never be 1.
If it becomes a 1, then it is a happy numbers. Otherwise, it is an unhappy number.
Here is the math to make it more clear:
22 = 4
42 = 16
12 + 62 = 37
We kept doing the math above and it just started looping the same numbers and never got to 1. Since, we did not get to 1,
2 is an:
Unhappy Number
