            for(int j=; j<=i; j++){
                if(j== || i== || j==i){
                    triangle[i][j] = ;
                }else{
                    triangle[i][j] = triangle[i-][j-] + triangle[i-][j];
                }
                System.out.print(triangle[i][j] + "\t");
            }
            System.out.println();
