Dr. Purplesheep discovered a new class of materials, which are useful in converting solar energy to electrical energy. She has designed 25 unique materials that belong to this class, and she would like to identify the top 3 out of these 25 materials in terms of their effectiveness. Unfortunately, however, she does not have an experimental method that can be used to quantify the effectiveness of a given material. Instead, she can run comparative experiments such that each experiment provides a ranking of 5 materials in terms of their effectiveness (from most effective to least effective). Running these experiments is rather expensive, so she would like to minimize the number of experiments she runs. Required:
a. Can you help her design a strategy that will identify the 3 most effective materials among 25 materials by performing the minimum number of experiments?
b. What is the minimum number of experiments needed to conclusively determine the 3 most effective materials? You do not need to write pseudo-code; a verbal explanation, possibly supported by graphics, will suffice

answer; wireshark;

we can all learn from our past mistakes because we all have different ways of learning different types of techniques. my way may or may not another classmate remember and have the repetition to acknowledge such standard. such as remembering acronyms. using abbreviations to us remember keep things in order in our memory. this us figure out what comes next in the sequence. if so, what we have is a sentence of just letters all in caps. we either know the meaning or have no idea what it stands for. most of the time we know the meaning and context. but most of us who don't know, should learn by having a quick glance at what needs to be remembered. such as repetition in the memory for acronyms. one way that me, is the fact that i'm always doing math and english assignments. so we have to remember specific meanings such as soapstone for documents, such as citing correctly. or pemdas for doing the equations correctly, even if it's the super long way. this works for everyone. you just have to find what works for you by practicing and repetition daily.
