Question

在hackerrank（node.js）上使用ProcessData包装函数了解如何运行我的代码时遇到一些麻烦。似乎我不能使用ProcessData包装器中的参数删除函数而不返回〜对stdout~没有响应。如何将他们的输入（一个整数字符串）传递给我的函数并获得某种响应，以便我可以调试？肯定会得到帮助。请参阅我的功能，编码环境，输入和输入。预期产量低于。谢谢！

    /*

     Input Format

    The first line contains two space-separated integers 
denoting the respective values of  (the number of integers) 
and  (the number of left rotations you must perform). 
    The second line contains  space-separated integers 
describing the respective elements of the array's initial state.

/*Environment with my code, below (how do I pass input as an argument to this function?? 
console.log or return the data, and get a response for debugging?)*/

function processData(input) {
    //Enter your code here
    var rotate = function(num,turns,ar){
    var store = ar.slice(0, turns);
    for(var i=0; i<store.length; i++){
        ar.shift();
        ar.push(store[i]);
    }
    return ar;
};
} 

process.stdin.resume();
process.stdin.setEncoding("ascii");
_input = "";
process.stdin.on("data", function (input) {
    _input += input;
});

process.stdin.on("end", function () {
   processData(_input);
});

Answer 1

您需要使用process.stdout.write。例如：

function processData(input) {
    //Enter your code here
    process.stdout.write('5 1 2 3 4');
}

Answer 2

代替使用
让输入= 4; // 4是整数变量

function processData（input）{

//在输出整数之前，您需要使用toString（）将其转换为字符串；

process.stdout.write(input.toString().trim());

}

//注意输出已转换为字符串
输出：4
