C :

#include<stdio.h>
int main()
{
    int n;
    while(scanf("%d",&n)!=EOF)
    {
        printf("%d",n);
        while(1)
        {
            if(n%2==0)
            {
                printf("-%d",n/2);
                n=n/2;
            }
            else
              {
                      printf("-%d",n+1);
                      n=n+1;
              }
            if(n==1)
                break;
        }
        printf("\n");
    }
}

C++ :

#include <stdio.h>
int n;
void run()
{
	printf("%d",n);
	while(n!=1)
	{
		if(n%2==1)
			n++;
		else
			n/=2;
		printf("-%d",n);//这道题唯一值得注意的地方就是不要输出多余的减号！！！每行里减号比数要少一个，所以注意判断。 
	}
	printf("\n");
}
int main()
{
	while(scanf("%d",&n)!=EOF)
		run();
	return 0;
} 

Java :

import java.util.*;
public class Main {
            public static void main(String[] args) { 
              Scanner input = new Scanner(System.in) ;

                    else {n=n+1;System.out.print(n);}
                    if(n!=1) System.out.print("-");
                    else  System.out.println();
