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.

Answer:
class Solution {
public:
void merge(int A[], int m, int B[], int n) {
int pos = m + n -1;
while( m>0 && n>0)
{
if( A[m-1] < B[n-1])
{
A[pos] = B[n-1];
pos--;
n--;
}
else
{
A[pos] = A[m-1];
pos--;
m--;
}
}
while( n >0)
{
A[pos] = B[n-1];
pos--;
n--;
}
}
};
