        for(int i=0; i<10; i++){
            triangle[i] = new int[i+1];
            for(int j=0; j<=i; j++){
                if(j==0 || i==0 || j==i){
                    triangle[i][j] = 1;
                }else{
                    triangle[i][j] = triangle[i-1][j-1] + triangle[i-1][j];
                }
                System.out.print(triangle[i][j] + "\t");
            }
            System.out.println();
