## Description
<section id="description">如果添加自然数大于零的整数的数字的平方则始终以1或89结尾 <pre> 15 - &gt; 26 - &gt; 40 - &gt; 16 - &gt; 37 - &gt; 58 - &gt; 89
7 - &gt; 49 - &gt; 97 - &gt; 130 - &gt; 10 - &gt; 1 </pre>编写一个函数该函数将数字作为参数并在执行上述过程后返回1或89。 </section>
## Instructions
<section id="instructions">
</section>
## Tests
<section id='tests'>
```yml
tests:
- text: <code>iteratedSquare</code>应该是一个函数。
testString: assert(typeof iteratedSquare=='function');
- text: <code>iteratedSquare(4)</code>应该返回一个数字。
testString: assert(typeof iteratedSquare(4)=='number');
- text: <code>iteratedSquare(4)</code>应该返回<code>89</code> 。
testString: assert.equal(iteratedSquare(4),89);
- text: <code>iteratedSquare(7)</code>应该返回<code>1</code> 。
testString: assert.equal(iteratedSquare(7),1);
- text: <code>iteratedSquare(15)</code>应该返回<code>89</code> 。
testString: assert.equal(iteratedSquare(15),89);
- text: <code>iteratedSquare(20)</code>应该返回<code>89</code> 。
testString: assert.equal(iteratedSquare(20),89);
- text: <code>iteratedSquare(70)</code>应该返回<code>1</code> 。
testString: assert.equal(iteratedSquare(70),1);
- text: <code>iteratedSquare(100)</code>应该返回<code>1</code> 。
testString: assert.equal(iteratedSquare(100),1);
