楼主能帮我看一下哪错了吗。。。ac不能过

var line = parseInt(read_line()); // 读取第一个数字

var hashTable = {};

for (var n=0; n < line; n++) {

var str = read_line();

    hashTable[str] = true;

}

var outputline = parseInt(read_line()); // 读取第二个数字

var middle = [];

for (var m=0;m<outputline; m++) {

var str = read_line();

    middle.push(str);

}

for (var j =0,len=middle.length; j <len; j++) {

    var temp = middle[j];

hashTable[temp] = false;  // 点过的设为false

}

var ret = [];

var keys = Object.keys(hashTable);

for (var i = 0; i < keys.length; i++) {

    var temp = keys[i]

if (hashTable[temp] === true ) {  // 取出没点过的

    ret.push(hashTable[temp])

    }

}

ret = ret.sort();

ret.forEach(function (str) {

    print(str)

})
