Algorithm

Start
Let i be an integer number.
Let j be an integer number.
Let row be an integer number and initialize by 6.
Let coe be an integer number and initialize by 0.
Repeat step 7 to 14 until all value parsed.
Set i = 0 and check I <= row;
Set j = 1 and check j <= row-i;
Print space.
check if j==0 || i==0
set coe = 1;
Else
Set coe = coe * (i+j-1)/j;
Print coe.
End

        int coe=1,rows = 6;

                else  
                    coe = coe * (i - j + 1) / j;  
  
                System.out.printf("%4d", coe);
