# Generic LRU cache

Implement **`solution.ts`** exporting a generic class:

```ts
export class LRUCache<K, V> {
  constructor(capacity: number);
  get key: K | void | undefined;
  put key: K | void |;
  size: number |;
}
```

```js
export class LRUCache<K, V> {
  constructor(capacity: number);
  get key: K | void |;
  put key: K | void |;
  size: number |;
}
```
