Of course! How silly of me.
What's a f***ing happy number?
According to Wikipedia:A happy number is defined by the following process. Starting with any positive integer, the following process can be applied: replace the number by the sum of the squares of its digits, and 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 numbers and those that do not are unhappy numbers.
Your teasers are hard.
That's the nicest thing anyone's said to me in a long time :)
