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 mand n respectively.
public class Solution {
public void merge(int A[], int m, int B[], int n) {
if(n==0) return;
int i=m-1;
int j=n-1;
for(int k=m+n-1;k>=0;k--){
if(i<0 && j>=0){
A[k]=B[j--];
}
else if(i>=0 && j<0){
A[k]=A[i--];
}
else if(A[i]>=B[j]){
A[k]=A[i--];
}
else if(A[i]<B[j]){
A[k]=B[j--];
}
}
}
