测试：

var arr=["学生12","学生1","学生三百五","学生2","学生十五"];
    
    arr.sort(compare)
    
    ----------------------------------------------------------
    
    (5) ["学生1", "学生2", "学生12", "学生十五", "学生三百五"]
    0: "学生1"
    1: "学生2"
    2: "学生12"
    3: "学生十五"
    4: "学生三百五"
    length: 5
    __proto__: Array(0)
