使用两个指针遍历数组,一个指向数值为0的元素,另一个指向数值不为0的元素,在遍历的过程中,不断交换两个指针的值。 例如, 比较简单的一道题。 [Code] 1: class Solution { 2: public: 3: voidmoveZeroes(vector<int>& nums) { 4:for(int zero_index =0, none_zero_index =0; 5: none_zero_index...
classSolution{public:voidmoveZeroes(vector<int>& nums){autoe = nums.end();//保存初始状态下数组的尾迭代器for(autoit = nums.begin(); it != nums.end();){if(it != e){//如果还没到达末尾if(*it ==0){//判断是否为0it = nums.erase(it);//删除操作会更新当前的迭代器nums.push_back(0...
Leetcode 283:Move Zeroes Leetcode 283:Move Zeroes Given an array nums, write a function to move all 0'sto the end of it while maintaining the relative order of the non-zero elements. 几个要点: 将 0 全部移动到数组后面 不打算非 0 元素的顺序 [法1] 暴力法 ......
leetcode 73 Set Matrix Zeroes 详细解答 leetcode 73 Set Matrix Zeroes 详细解答 解法1 此题如果空间复杂度为O(MN),则题目简单,只需要将为0的下标用一个集合保存起来,然后再判断所遍历的数字是否在集合内。 但根据题目要求,最好不要用空间复杂度为O(MN)的方法来做 解法2 只申请两个set用以保存数值为0...
Hint Given an integer arraynums, move all0's to the end of it while maintaining the relative order of the non-zero elements. Notethat you must do this in-place without making a copy of the array. Example 1: Input:nums = [0,1,0,3,12]Output:[1,3,12,0,0] ...
