Pascal Triangle and Fibonacci














Code - Fibonacci and Pascal Triangle

m=10;
   pt=PASCALTRIANGLE(m);
   a=pt
      .map(
       function(r,i)
        {
         var prefix=(REPEATCHAR(" ",(2*m-(2*i+1))/2).split(""));
           return(
                prefix
                 .concat(r.join(", ,").split(","))
                 .concat(prefix)
            )
        }
     );
 (a);

FIBONNACI(100)

b=PASCALTRIANGLE(100)
b.map(
   	function calcfib(r,i,d)
  	{
      		var fib=0;
    		var j=0;

       	   		j++;
        	   	}
             		return(fib)
          	}
