A dog and cat-only animal refuge rigidly follows the principle of "first in, first out." People can choose whether they would prefer a dog or a cat (and would receive the oldest of that species) or they must adopt the animal that is "oldest" (based on arrival time) of all animals at the shelter. They are unable to pick the precise animal they want. Create the necessary data structures and put enqueue, dequeueAny, dequeueDog, and dequeueCat into action. The internal Linkedlist data structure is available for usage.

Computing Algorithms

A computing algorithm is a set of instructions or a process for solving computational problems. In other words, it contains a set of rules that indicate the step-wise process to solve a problem. The algorithm takes a set of inputs, executes the instructions given to it, and produces the desired output.
