Write a function with type:
guess5 : int -> bool * intwith the following behaviour.
When guess5 is applied to a parameter n, it first checks if n is in the range 1..5;
if not, it fails.
Otherwise, it generates a random number r between 1 and 5, and it returns a pair (b,r),
where b is true iff n equals to r.
Hint. Use the function:
Random.int(n)to generate a random integer in the range 0..n-1.
