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.
For example, given nums = [0, 1, 0, 3, 12], after calling your function, nums should be [1, 3, 12, 0, 0].
Note:
You must do this in-place without making a copy of the array.
Minimize the total number of operations.
public class Solution {
public void moveZeroes(int[] nums) {
int i=0;
int j=0;
while(j<nums.length){
if(i==j) j++;
if(j==nums.length) break;
if(nums[i]==0)
{
if(nums[j]!=0)
{
nums[i]=nums[j];
nums[j]=0;
i++;
}
else
j++;
}
else i++;
}
}
}
本文介绍了一种不使用额外数组空间的方法,将数组中所有零元素移动到数组的末尾,同时保持非零元素的相对顺序。该方法通过双指针技术实现,旨在减少操作次数并提高效率。
