拆分一个整数

import java.util.Scanner;
//拆分整数(相加)
public class Test {
    static int[]res=new int[100];
    static int p=0;
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        int m =sc.nextInt();
        resolve(m,1);
    }
    static void resolve(int m,int n){
        if(m<=0){
            for(int i=0;i<res.length;i++){
                if(res[i]!=0)
                System.out.print(res[i]+" ");
            }
            System.out.println();
        }
        for(int i=n;i<=m;i++){
            res[p] = i;
            p++;
            resolve(m-i,i);
            p--;
            for(int j=p;j<res.length;j++)
                res[j]=0;
        }
    }

}
