leetcode 283. Move Zeroes
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.
void moveZeroes(int* nums, int numsSize) {
for(int i=numsSize-1;i>=0;i--)
{
if(nums[i]==0)
{
continue;
}
int j;
for(j=i-1;j>=0;j--)
{
if(nums[j]==0)
{
int k=nums[i];
nums[i]=nums[j];
nums[j]=k;
break;
}
}
if(j==-1)
{
return nums;
}
}
return nums;
}
Input:[0,1,0,3,12]
for(int i=0;i<numsSize;i++)
{
if(nums[i]!=0)
{
continue;
}
int j;
for(j=i+1;j<numsSize;j++)
{
if(nums[j]!=0)
{
int k=nums[i];
nums[i]=nums[j];
nums[j]=k;
break;
}
}
if(j==numsSize)
{
return nums;
}
}
return nums;
}
本文提供了一种有效的解决方案来解决LeetCode上的283题“Move Zeroes”。该题要求将数组中所有0元素移动到末尾,同时保持非零元素的相对顺序。文章详细介绍了通过双循环实现这一目标的正确方法,并对比了错误的实现方式。
