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 nums1and nums2 are m and n respectively.
class Solution { public: void merge(vector<int>& nums1, int m, vector<int>& nums2, int n) { int k = m+n-1; int i=m-1,j=n-1; while(k>=0 && i>=0 && j>=0){ if(nums1[i] > nums2[j]){ nums1[k--] = nums1[i--]; }else{ nums1[k--] = nums2[j--]; } } while(i>=0){ nums1[k--] = nums1[i--]; } while(j>=0){ nums1[k--] = nums2[j--]; } } };
