算法练习：求最大值和最小值

情景看来不需要算法，如果真需要算法的话，给你一个递推方程：
f(n-10,n)=Max[f(n-10,n-1)+num[n],f(n-10,n-1)] (n>=10)

markdown 不支持反引号引导的代码块。。。

var Data = {
    init: function() {
        this.interval(1000);
    },
    pool: [],
    maxCount: 10000,
    holdCount: 100,
    generate: function() {
        var num = Math.ceil(Math.random() * 10000);
        this.pool.push(num);
        if (this.pool.length > this.maxCount) {
            this.pool.splice(0, this.pool.length - holdCount);
        }
    },
    interval: function(interTime) {
        var self = this;
        setInterval(function() {
            self.generate();
        }, interTime);
    }
}

function getNum(count, Data) {
	var data=Data.pool;
    Data.holdCount=count;
    var sets = data.slice(data.length - count, data.length);
    console.log(sets);
    console.log("Max is : ", Math.max.apply(null, sets));
    console.log("Min is : ", Math.min.apply(null, sets));
}

Data.init();

getNum(10, Data);

代码已完成，没什么算法，就为了打非要算法人的脸。还有我的 500 奖励坐着到账
