[Charles Babbage](https://en.wikipedia.org/wiki/Charles_Babbage "wp: Charles_Babbage"), looking ahead to the sorts of problems his Analytical Engine would be able to solve, gave this example:
<blockquote>
What is the smallest positive integer whose square ends in the digits 269,696?
<footer style="margin-left: 2em;">Babbage, letter to Lord Bowden, 1837; see Hollingdale and Tootill, <i>Electronic Computers</i>, second edition, 1970, p. 125.</footer>

</blockquote>
He thought the answer might be 99,736, whose square is 9,947,269,696; but he couldn't be certain.
The task is to find out if Babbage had the right answer.

## Instructions
<section id='instructions'>
# --instructions--
Implement a function to return the lowest integer that satisfies the Babbage problem. If Babbage was right, return Babbage's number.
</section>
## Tests
<section id='tests'>
# --hints--
```yml
tests:
- text: <code>babbage</code> should be a function.
testString: assert(typeof babbage === 'function');
- text: <code>babbage(99736, 269696)</code> should not return 99736 (there is a smaller answer).
testString: assert.equal(babbage(babbageAns, endDigits), answer);
`babbage` should be a function.
```js
assert(typeof babbage === 'function');
```
</section>
`babbage(99736, 269696)` should not return 99736 (there is a smaller answer).
