三元组的js实现

var triplet = {
    v: [undefined, undefined, undefined],
    initTriplet: function (v1, v2, v3) {
        this.v[0] = v1;
        this.v[1] = v2;
        this.v[2] = v3;
    },
    get: function (index) {
        return this.v[index];
    },
    put: function (index, value) {
        this.v[index] = value;
    },
    isAscending: function() {
        return this.v[0] <= this.v[1] && this.v[1] <= this.v[2];
    },
    isDescending: function() {
        return this.v[0] >= this.v[1] && this.v[1] >= this.v[2];
    },
    max: function() {
        return Math.max.apply(null, this.v);
    },
    min: function() {
        return Math.min.apply(null, this.v);
    }
};
