Bakery Quality Control

This coding exercise is worth a total of $10$ points, each test is worth one point.

Your program controls boxes of pastries coming out of a bakery. For each produced box, you are

required to compare its contents to a list of expected items $($its "template"$)$ and determine whether

the box is correct or not. The contents of a box is described by a string such as $"$pcm$"$ for 'p'ie,

'c'ookie, and 'm'uffin, or $"$ddp$"$ for 'd'onut, 'd'onut, and 'p'ie. The template is described in the same

manner. So given a list of $($box$,$ template$)$ pairs, your program should indicate how many times

it found a mismatch between a box and its template and return that total.

A box contains no more than $10$ items, and there are no more than $1000$ boxes to check at a time.

Items in a box can be repeated, so $"$cc$"($cookie cookie$)$ is not the same as $"$c$"($cookie$).$ Items are

not ordered, so the box $"$cm$"($cookie$,$ muffin$)$ matches the template $"$mc$"($muffin$,$ cookie$).$

Example:

Your program is provided with the following list:

$[[cm,mc],$

$[ccm,mc],$

$[pm,mc],$

$[c,mc]]$

The pair $["$cm$","$mc$"]$ is valid; the order of items in the box doesn't matter.

The pair $["$ccm$","$mc$"]$ is invalid; there are too many cookies in the box.

The pair $["$pm$","$mc$"]$ is invalid; there is a pie in the box, and no cookie.

The pair $["$c$","$mc$"]$ is invalid; there is a muffin missing in the box.

Given that list, your program should return $3,$ as it found $3$ invalid boxes out of $4.$
