Q$1)$ write a program that displays the following

:menu

find max perfect number $-1$

calculate series $-2$

exit $-3$

If the user press $1$ : the program reads $2$

numbers from the user A and $B$ then the

program should print the maximum perfect

$.$number between A and $B$

If the user press $2$: the program should

:calculate the following series

$f(x)=a-(1^{**}\frac{a}{2^{{?}^{{?}^{?}}}}1)+(3^{**}\frac{a}{4^{{?}^{{?}^{?}}}}3)-(5^{**}\frac{a}{6^{{?}^{{?}^{?}}}}5)dotsdots..$

$(n^{**}\frac{a}{(n+1{)}^{{?}^{{?}^{?}}}}n)$

Where a and $n$ are user input integers

If the user press $3$ : the program stops
