LeetCode283:Move Zeros

时间:2022-10-25 00:32:01

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:

  1. You must do this in-place without making a copy of the array.
  2. Minimize the total number of operations.

主要思路:保持两个指针,保证两个指针之间[zero_bit,nonzero_bit)范围内都是0,然后调换首个0和首个非零

  1. void moveZeroes(int* nums, int numsSize)
    {
    int zero_bit = ;
    int nonzero_bit = ;
    while(nonzero_bit<numsSize)
    {
    if(nums[nonzero_bit] != )
    {
    if(nonzero_bit != zero_bit)
    {
    nums[zero_bit++] = nums[nonzero_bit];
    nums[nonzero_bit] = ;
    }else{
    ++zero_bit;
    }
    }
    ++nonzero_bit;
    }
    }
