import console; 



var 判断合法日期 = function( year=0, month=0, day=0 ){

    if(    (year<=0) || (month<=0) || (month>12) || (day<=0) ){

        return false; 

    }

    bigMonth = {1,3,5,7,8,10,12};

    smallMonth = {4,6,9,11};

    

    if(month=2){

        if(((year%4 == 0) && (year%100 !=0)) || (year%400==0)){

            if(day>29) return false;

        }else{

            if(day>28) return false;

        }

    }

    if(null != table.find(bigMonth,month) && (day>31)){

        return false

    }

    if(null != table.find(smallMonth,month) && (day>30)){

        return false

    }

    return true; 

}



console.dump(判断合法日期(2012 , 2 , 42));

console.pause(true);
