Program by Luck..

[pinch_hitter]

While implementation the Pascal Triangle, I observed some symmetry pattern in the output of the program. Afterward I made some change in the actual Pascal code, like printing only a specific digit else white space and converting double digit to single digit (n%10);

Uses : java Pascal

Pascal.javapublic class Pascal{

public static void main(String[] args){

int n = Integer.parseInt(args[0]);
                int p = Integer.parseInt(args[1]);
                String str =  args[2].trim();

for(int i=0;i                        String out="";
                        for(int k=0;k<(n-i);k++)
                                out+= " ";

for(int j=0; j < (i+1); j++){
                                Float f = new Float((fac(i)/(fac(j)*fac(i-j)))+"");
                                int nn  = f.intValue()%10;

if(Integer.parseInt(args[1]) == -1)
                                        out += nn+ " ";

else if( nn == p){
                                        out += str+ " ";
                                }
                                else
                                        out += "  ";
                        }
                        System.out.println(out);
                }
        }
        static float fac(int n){
                float f=1;
                for(int i=1;i<=n;i++)
                        f*=i;
        return f;
        }
}

1st parameter:    Number of iteration  [eg. 50]
2nd parameter:  which number want to replace [eg: 4,6, 7]
3rd parameter:  which character want to print; [eg: * ,^, !]
