using Primes

function Triangle(n)  
return sum(1:n)  
end

num=1  
temp=3  
while num\<500

```
A=collect(factor(Triangle(temp)))
if prod(i->A[i][2]+1, 1:length(A) )<500
    temp+=1
else
    num=5000
    ans=Triangle(temp)
end

```

end  
print(ans," " ,Triangle(temp))

I’m puzzled by why ans gives nothing, while its expected to be 76576500. Any explanation will be greatly appreciated.

I figured it out.  
ans is probably one of the keywords in Julia.  
So use a different name solves the problem.
