Please write an anonymous PL$/$SQL program to check whether the number $1001$ is a prime number $($a number that cannot be divided by any number other than $1$ and itself$).$ Print out a message $\text{'}1001$ is a prime number $\text{'}$ if $1001$ is a prime number and $\text{'}1001$ is not a prime number' otherwise.

Hint: You can check whether $1001$ can be divided by any odd integer that is greater than $1$ but less or equal to square root of $1001.$

sqrt$($x$)$ returns square root of x in PL$/$SQL$.$ mod$($x$,$y$)$ returns remainder of dividing x by y$.$
