Given two sorted integer arrays A and B, merge B into A as one sorted array.
Note:
You may assume that A has enough space (size that is greater or equal to m + n) to hold additional elements from B. The number of elements initialized in A and B are m andn respectively.
思路：list自带的有归并函数，所以把两个数组分别放入两个list中，然后归并，再把排好序的归并结果放入数组A中；代码如下：
1 class Solution { 2 public: 3 void merge(int A[], int m, int B[], int n) { 4 list<int> la; 5 list<int> lb; 6 for(int i=0;i<m;i++) 7 { 8 la.push_back(A[i]); 9 } 10 for(int i=0;i<n;i++) 11 { 12 la.push_back(B[i]); 13 } 14 la.sort(); 15 lb.sort(); 16 la.merge(lb); 17 for(int i=0;i<m+n;i++) 18 { 19 A[i]=la.front(); 20 la.pop_front(); 21 } 22 23 } 24 };
