--description--

Given an array of hours worked today per person, return the number of pizzas to order for a pizza party.

• Divide each person's hours worked by 3 to get their slice count.
• You can't eat a partial slice, so round each person's slice count up to the nearest whole number.
• Each person gets a minimum of two slices.
• Each pizza has 8 slices. Round the total number of pizzas up to the nearest whole pizza.

--hints--

getPizzasToOrder([8, 8, 8]) should return 2.

assert.equal(getPizzasToOrder([8, 8, 8]), 2);

getPizzasToOrder([10, 9, 8, 2, 2, 6, 10]) should return 3.

assert.equal(getPizzasToOrder([10, 9, 8, 2, 2, 6, 10]), 3);

getPizzasToOrder([1, 2, 3, 4, 5]) should return 2.

assert.equal(getPizzasToOrder([1, 2, 3, 4, 5]), 2);

getPizzasToOrder([8, 8, 8, 8, 8, 8, 8, 8]) should return 3.

assert.equal(getPizzasToOrder([8, 8, 8, 8, 8, 8, 8, 8]), 3);

getPizzasToOrder([9, 9, 6]) should return 1.

assert.equal(getPizzasToOrder([9, 9, 6]), 1);

getPizzasToOrder([10, 12, 16, 9, 8, 11, 15, 8, 0]) should return 5.

assert.equal(getPizzasToOrder([10, 12, 16, 9, 8, 11, 15, 8, 0]), 5);
