Design an LRU Cache
Implement a data structure that follows the Least Recently Used eviction policy with O(1) get and put operations.
Level 14 2,450 / 3,800 XP
🔥 12 day streak
solution.ts
class LRUCache<K, V> {
  private map = new Map<K, V>();

  constructor(
    private capacity: number
  ) {}

  get(key: K): V | undefined {
    const val = this.map.get(key);
    if (val !== undefined) {
      this.map.delete(key);
      this.map.set(key, val);
    }
    return val;
  }
}
✨ Claude: Good approach using Map ordering. Consider adding a put() method that handles eviction when capacity is exceeded. The generic types are a nice touch.
