队列

题号剑指 Offer 09. 用两个栈实现队列

今天休息做点简单题

class CQueue {
    private nums = []
    constructor() {
    }

    appendTail(value: number): void {
        this.nums.push(value)
    }

    deleteHead(): number {
        if(this.nums.length===0)return -1
        return this.nums.shift()
    }
}

/**
 * Your CQueue object will be instantiated and called as such:
 * var obj = new CQueue()
 * obj.appendTail(value)
 * var param_2 = obj.deleteHead()
 */
