将数组中负数调到正数之前，但相对位置不变

public class Sort{
public static void main(String[]args){
int []A={1,2,-3,-4,5,6,-1,10};
sort(A,0,A.length-1);
for(int i=0;i<A.length;i++){
System.out.print(A[i]+" ");
}
}
public static void sort(int []A,int low,int high){
if(low<high){
int mid=(low+high)/2;
sort(A,low,mid);
sort(A,mid+1,high);
merge(A,low,mid,high);
}
}
public static void merge(int []A,int low,int mid,int high){
int []temp=new int[high-low+1];
int h1=low,h2=mid+1,i=0;
while(h1<=mid&&A[h1]<0){
