Solve with Coral program, pseudocode and code.

The program calculates awards points for a book club. The club awards points to its customers based on the number of books purchased per month. If a number of books purchased inputted is less than $0,$ prompt the user to re$-$enter until a value is valid. The points are awareded as follows:

If a customer purchased $0$ books, he$/$she earns $0$ point.

If a customer purchased $1$ books, he$/$she earns $5$ points.

If a customer purchased $2$ books, he$/$she earns $15$ points.

If a customer purchased $3$ books, he$/$she earns $30$ points.

If a customer purchased $4$ or more books, he$/$she earns $60$ points.

$($Notes: The processing function may need two parameters, and returns points earned. Please use a multiple$-$alternative decison structure since only one decidion is made. DO NOT use separate single$-$alternative if sets.$)$ming language in Pseudocode and coral code.
