leetcode,查找并移动某字符

    问题:

    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

    思路:两个指针,一个指向“0”,一个指向非“0”,从左向右,如果找到,则交换

    代码:

     public void moveZeroes(int[] nums) {         int i = 0;         int j = 0;         while(j < nums.length){             if(nums[j] != 0){                 if(j !=i ){                     nums[i] = nums[j];                     nums[j] = 0;                     i++;                 }                 else{                     ++i;                 }             }             ++j;         }     }
