題目

Given an array nums, write a function to move all 0's to the end of it while maintaining the relative order of the non-zero elements.

題意

將陣列中為0的元素，移至陣列最後方。

Example:

Input: [0,1,0,3,12]
Output: [1,3,12,0,0]

解題想法

可用splice方法將0取出，再用push方法添加至陣列的後方。

Solution

var moveZeroes = function (nums) {
  let x = 0;
  for (let i = 0; i < nums.length - x; i++) {
    if (nums[i] === 0) {
      nums.push(parseInt(nums.splice(i, 1).join('')));
      i--;
      x++;
    }
  }
  return nums;
};
