Write a nested if end statement based off this criteria:

Evaluate if the first element of nums$\_$vec is greater than $4.$

If it is$,$ then check if first element of nums$\_$vec is less than $10.$

If it is greater than $4,$ and less than $10($satisfying both the conditions above$),$ subtract $4$ from the first element of nums$\_$vec, saving this new value to that first element of nums$\_$vec.

Then, set a variable called is$\_$one$\_$or$\_$ten to $0$

Now, write a switch case based off this criteria:

In the case that the first element of nums$\_$vec is $1,$ set is$\_$one$\_$or$\_$ten to $1$

In the case that the first element of nums$\_$vec is $10,$ set is$\_$one$\_$or$\_$ten to $2$
