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 and n respectively.

 class Solution { public: void merge(int A[], int m, int B[], int n) {int end = m + n -1;while(m > 0 && n >0){if (A[m-1] >= B[n-1])A[end--] = A[--m];elseA[end--] = B[--n];}if (n > 0)memcpy(A, B, sizeof(int) * n); } };
