1. 遍历所有数组，统计0的个数
2. 倒着把零写入数组末尾

func moveZeroes(nums []int)  {var count, j intfor _, key := range nums {if key == 0 {count++} else{nums[j] = keyj++}}for i:=len(nums) - count; i < len(nums); i++ {nums[i] = 0}
}

最优解(快慢指针)

减少了数组赋值次数

func moveZeroes3(nums []int) {j := 0for i := 0; i < len(nums); i++ {if nums[i] == 0 {continue}nums[j] = nums[i]if i != j {nums[i] = 0}j++}
}
