# --description--
Using a combination of black square tiles and oblong tiles chosen from: red tiles measuring two units, green tiles measuring three units, and blue tiles measuring four units, it is possible to tile a row measuring five units in length in exactly fifteen different ways.
How many ways can a row measuring fifty units in length be tiled? NOTE: This is related to Problem 116.
# --hints--
`euler117()` should return 100808458960497.
```js
assert.strictEqual(euler117(), 100808458960497);
```
# --seed--
## --seed-contents--
```js
function euler117() {
return true;
}
euler117();
```
# --solutions--
```js
// solution required
```
