Question

我正在研究代码战争问题，我的任务是将全零移动到数组的末尾，而不移动所述数组中任何其他元素的位置。我遍历数组，确定是否找到0，然后将其拼接到数组之外，同时将0添加到第二个数组。在函数末尾，我将两个数组合并并返回。

var moveZeros = function (arr) {
  // TODO: Program me
  var Zeros = [];

  for (var i = 0; i < arr.length; i++) {
    if(arr[i] === 0){
      arr.splice(i, 1);
      Zeros.push(0);
    }
  }

  return arr.concat(Zeros);

  //loop through arr
    //if arr[i] is 0
      //take out of arr and push into newarr

  //return arr + newarr
}

对于测试案例，我知道我通过了什么输入。但是我没有通过三个测试用例：

Expected: '[9,9,1,2,1,1,3,1,9,9,0,0,0,0,0,0,0,0,0,0]', instead got: '[9,0,9,1,2,1,1,3,1,9,0,0,9,0,0,0,0,0,0,0]'
Expected: '["a","b","c","d",1,1,3,1,9,9,0,0,0,0,0,0,0,0,0,0]', instead got: '["a",0,"b","c","d",1,1,3,1,9,0,0,9,0,0,0,0,0,0,0]'
Expected: '["a","b",null,"c","d",1,false,1,3,[],1,9,{},9,0,0,0,0,0,0,0,0,0,0]', instead got: '["a",0,"b",null,"c","d",1,false,1,3,[],1,9,0,{},0,9,0,0,0,0,0,0,0]'

如您所见，它们显示了预期的输出，但没有显示输入，因此我无法调试问题。有人可以给我一些有关我哪里出问题/我想念什么的见解吗？
