There are four types of common coins in [US](https://en.wikipedia.org/wiki/United_States) currency:
|
||||
|
||||
<ul>
|
||||
<li>quarters (25 cents)</li>
|
||||
<li>dimes (10 cents)</li>
|
||||
<li>nickels (5 cents), and</li>
|
||||
<li>pennies (1 cent)</li>
|
||||
</ul>
|
||||
|
||||
<p>There are six ways to make change for 15 cents:</p>
|
||||
|
||||
<ul>
|
||||
<li>A dime and a nickel</li>
|
||||
<li>A dime and 5 pennies</li>
|
||||
<li>3 nickels</li>
|
||||
<li>2 nickels and 5 pennies</li>
|
||||
<li>A nickel and 10 pennies</li>
|
||||
<li>15 pennies</li>
|
||||
</ul>
|
||||
|
||||
# --instructions--
|
||||
|
||||
Implement a function to determine how many ways there are to make change for a dollar using these common coins (1 dollar = 100 cents)
|
||||
|
||||
# --hints--
|
||||
|
||||
`countCoins`是一个函数。
|
||||
`countCoins` should be a function.
|
||||
|
||||
```js
|
||||
assert(typeof countCoins === 'function');
|
||||
```
|
||||
|
||||
`countCoints()`应该返回242。
|
||||
`countCoins()` should return 242.
|
||||
|
||||
```js
|
||||
assert.equal(countCoins(), 242);
