Sally's Pizza is bringing its pizza ordering system into the digital age

to get better customer insights.

They've encoded each of Sally's pizzas and other dishes as an integer:

$*10$: small, cheese $20$: medium, cheese $30$: large, cheese

$*11$: small, pepperoni $21$: medium, pepperoni $31$: large, pepperoni

$*---$

$*40$: calzone

$*41$: spaghetti pie

$*42$: baked ziti

$*/$

$//$ You can use these constants in your solutions.

private final int SMALL$\_$CHEESE $=10$;

private final int SMALL$\_$PEPPERONI $=11$;

private final int MEDIUM$\_$CHEESE $=20$;

private final int MEDIUM$\_$PEPPERONI $=21$;

private final int LARGE$\_$CHEESE $=30$;

private final int LARGE$\_$PEPPERONI $=31$;

private final int CALZONE $=40$;

private final int SPAGHETTI$\_$PIE $=41$;

private final int BAKED$\_$ZITI $=42$;

$/*$

Each customer order, consisting of one or more items, is represented as an array

where each value represents an item in that order.

Create an "order" that contains the following items:

$*-$ small, cheese $($SMALL$\_$CHEESE$)$

$*-$ calzone $($CALZONE$)$

$*-$ large, pepperoni $($LARGE$\_$PEPPERONI$)$

$*-$ spaghetti pie $($SPAGHETTI$\_$PIE$)$

Examples:

createOrder$()->[10,40,31,41]$

public int$[]$ createOrder$()\{$

return new int$[]\{\}$;

$\}$

$/*$

Sally realized that she needed to know how many calzones her shop sells per day.

Implement the logic to count the number of calzones sold per day when given an

array representing each item that her customers ordered that day.

Examples:

getCalzoneSales$([$CALZONE$,$ LARGE$\_$CHEESE, LARGE$\_$PEPPERONI, CALZONE, SMALL$\_$CHEESE$])->2$

which is the same as:

getCalzoneSales$([40,30,31,40,10])->2$

getCalzoneSales$([$LARGE$\_$CHEESE, LARGE$\_$PEPPERONI, SMALL$\_$CHEESE$])->0$

getCalzoneSales$([])->0$

public int getCalzoneSales$($int$[]$ orders$)\{$

return $0$;

$\}$

$/*$

Sally also needs to know the total revenue for all cheese pizzas sold on any given day.

$*$ Each small cheese pizza costs $$8.$

$*$ Each medium cheese pizza costs $$11.$

$*$ Each large cheese pizza costs $$14.$

Implement the logic to return the total revenue of all cheese pizzas when given

an array representing each item that her customers ordered that day.

Examples:

getCheesePizzaRevenue$([$SMALL$\_$CHEESE$])->8$

getCheesePizzaRevenue$([$SMALL$\_$CHEESE, SMALL$\_$PEPPERONI, MEDIUM$\_$CHEESE$])->19$

getCheesePizzaRevenue$([$SMALL$\_$PEPPERONI, MEDIUM$\_$PEPPERONI$])->0$

public int getCheesePizzaRevenue$($int$[]$ orders$)\{$

return $0$;

$\}$
