       a=sc.nextInt();

       System.out.println("enter  side 2");

        b=sc.nextInt();

        System.out.println("enter  side 3");

        c=sc.nextInt();

        if(a<=0||b<=0||c<=0)

        System.out.println("sides should be positive...Not possible");

       if((a+b)<c||(a+c)<b||(b+c)<a)

       System.out.println("not possible");

       else if(a==b&&b==c)

       System.out.println("it's an equilateral triangle");
