Given two sorted integer arrays nums1 and nums2, merge nums2 into nums1 as one sorted array.
Note:
You may assume that nums1 has enough space (size that is greater or equal to m + n) to hold additional elements from nums2. The number of elements initialized in nums1 and nums2 are m and n respectively.
分别用 i, j 定位nums1 和 nums2 中的元素进行归并。
我的代码:
class Solution { public: void merge(vector<int>& nums1, int m, vector<int>& nums2, int n) { vector<int> nums; int i = 0, j = 0; while (i < m || j < n) { if (i < m && j < n) { if (nums1[i] < nums2[j]) nums.push_back(nums1[i++]); else nums.push_back(nums2[j++]); } else if (i < m) { while (i < m) nums.push_back(nums1[i++]); } else { while (j < n) nums.push_back(nums2[j++]); } } nums1.clear(); nums1 = nums; } };
