Helo!
Please, what is wrong wiht the code?
If I out a1=400, it writes out 19, a si t should be.
But, if I write 484, then it writes out NOTHING!!!
it should wirte out closest prime number to sqrt(a1).
For sqrt(400)=20, nearest prime is 19, and it writes it out.
But for sqrt(484)= 22, nearest pirme would be 23, and it writes nothing.
please, where is the mistake?
Many thanks!
