Merge Sorted Array
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.
分析:题意为 将两个整型有序数组合并为一个有序数组。
代码如下:
class Solution { public: void merge(vector<int>& nums1, int m, vector<int>& nums2, int n) { if(n<1) return; int k=m+n-1; int i=m-1; int j=n-1; while(i>=0 && j>=0){ nums1[k--]=nums1[i]>nums2[j]?nums1[i--]:nums2[j--]; } while(j>=0) nums1[k--]=nums2[j--]; } };
