Scanner in=new Scanner(System.in);
System.out.print("Enter a number : ");
int n=in.nextInt();
int sum=0,j=0;
System.out.println("The possible combinations:");
for(int i=1;i<n;i++)
{
sum=i;
j=i+1;
while(sum<n)
{
sum=sum+j;
j++;
}
if(sum==n)
{
for(int k=i;k<j;k++)
{
if(k==i)
System.out.print(k);
else
System.out.print("+" + k);
}
System.out.println();
}
}
}
