A script stores information on potential subjects for an experiment in a vector of structures called subjects. The following shows an example of what the contents might be: >> subjects (1) ans = name: 'Joey' sub_id: 111 height: 6.7000 weight: 222.2000 For this particular experiment, the only subjects who are eligible are those whose height or weight is lower than the average height or weight of all subjects. The script will print the names of those who are eligible. Create a vector with sample data in a script, and then write the code to accomplish this. Don't assume that the length of the vector is known; the code should be general.
An animal shelter, which holds only dogs and cats, operates on a strictly"first in, firstout" basis. People must adopt either the "oldest" (based on arrival time) of all animals at the shelter,or they can select whether they would prefer a dog or a cat (and will receive the oldest animal ofthat type). They cannot select which specific animal they would like. Create the data structures tomaintain this system and implement operations such as enqueue, dequeueAny, dequeueDog,and dequeueCat. You may use the built in Linkedlist data structure.

Some have stated that linked Stacks are much better than arrays; others said that Queues are mostly used than arrays are. If that is always valid, then why are arrays used at all? As a conclusion of what you have learnt about them, you are asked to compare Arrays with Stacks and Queues in terms of some areas. The below table includes 4 questions to be answered comparing between the three data structures. You are asked to complete this table with the proper answer, based on your knowledge and your research, and using your own words Case QUEUES ARRAYS STACKS Which principle is used? FIFO-LIFO- INDEXED, with a brief explanation. How do deletion/insertion take place? Dynamic or fixed size? For which problems they are the Best to use?
