-<p>幸福的数字由以下过程定义： </p><p>从任何正整数开始，将数字替换为其数字的平方和，并重复该过程直到数字等于1（它将保持不变），或者它在一个不包括1的循环中无休止地循环。这些数字这个过程在1结束的是幸福的数字，而那些不以1结尾的数字是不愉快的数字。 </p><p>实现一个函数，如果数字是满意的，则返回true，否则返回false。 </p>
+A [happy number](https://en.wikipedia.org/wiki/Happy_number) is defined by the following process:
+
+Starting with any positive integer, 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, while those that do not end in `1` are unhappy numbers.
+
+# --instructions--
+
+Implement a function that returns true if the number is happy, or false if not.
