func LFU(operators [][]int, k int) (ans []int)

设计 LFU 缓存结构

type Entry struct {
	Key  int // 键
	Val  int // 值
	Freq int // 频率
}

type LfuCache struct {
	// contains filtered or unexported fields
}

思路: 采用双 hash 表来记录数据

func NewLfuCache(capacity int) *LfuCache

func (l *LfuCache) Get(key int) (value int)

func (l *LfuCache) Set(key, value int)
