将数组向右移动，并将缺少的空格设为0

function shiftArrayRight(arr, shift) {
  if (shift > arr.length) {
    shift = shift % arr.length;
  }

  var newArr = new Array(arr.length).fill(0);

  for (var i = 0; i < arr.length; i++) {
    var newIndex = (i + shift) % arr.length;
    newArr[newIndex] = arr[i];
  }

  return newArr;
}

// 示例用法
var arr = [1, 2, 3, 4, 5];
var shift = 2;
var result = shiftArrayRight(arr, shift);
console.log(result); // 输出 [0, 0, 1, 2, 3]
