## Algorithmic Thinking (Part 1)

CAT Handbook.The Python Algorithms online test assesses candidates' algorithmic-thinking skills and their ability to implement algorithms using Python. It's an ideal test for pre-employment screening. A good developer will be able to design and implement algorithms that are both correct and efficient. Computational complexity is important not only when scaling applications but when creating responsive, maintainable, and efficient code. This online test requires candidates to analyze or design an algorithm using Python as the programming language.

If there are no ingredients or toppings, the method should return an empty list. When passed two lists of names, it will return a list containing the names that appear in either or both lists. The returned list should have no duplicates.

The premium question library contains our unique, hand-crafted questions. We offer a refund if you find any of them answered online. Python Algorithms Online Test TestDome skill assessments are used by more than 5, companies andindividual test takers.

Premium Questions The premium question library contains our unique, hand-crafted questions. Algorithmic thinking is one of the key traits of a good programmer, especially one working on complex or performance-critical code.

A queue is a collection of items that are maintained in a sequence and can be modified by the addition of entities at one end of the sequence and removal from the other end of the sequence. It is the collection to be used when first-in-first-out FIFO collection is needed. Every programmer should be familiar with data-sorting methods, as sorting is very common in data-analysis processes. A set is a collection of distinct objects.

It's one of the most used types of collection, alongside arrays, lists, and maps.There are a lot of ways to think about problem solving. This article will take on three of these that we are hearing more about recently: computational thinking, algorithmic thinking, and design thinking. While there are differences between each, they all blend critical thinking and creativity, follow iterative processes to formulate effective solutions, and help students embrace ambiguous and open-ended questions.

So, without further ado…. Computational thinking is a set of skills and processes that enable students to navigate complex problems. The computational thinking process starts with data as the input and a quest to derive meaning and answers from it. The output is not only an answer but a process for arriving at it. To be a map toward understanding, computational thinking plots the journey to ensure that the process can be replicated and others can learn from it and use it.

At this juncture, computational thinking often feeds into algorithmic thinking. Decomposition : Break the problem down into smaller, more manageable parts. Pattern Recognition : Analyze data and identify similarities and connections among its different parts. Abstraction : Identify the most relevant information needed to solve the problem and eliminate the extraneous details.

Algorithmic Thinking : Develop a step-by-step process to solve the problem so that the work is replicable by humans or computers. Computational Thinking Examples Computational thinking is a multi-disciplinary tool that can be broadly applied in both plugged and unplugged ways. These are some examples of computational thinking in a variety of contexts. Computational Thinking for Collaborative Classroom Projects To navigate the different concepts of computational thinking — decomposition, pattern recognition, abstraction, and algorithmic thinking — guided practice is essential for students.

Computational Thinking for Data-Driven Instruction In this examplethe New Mexico School for the Arts sought a more defined process for using data to better inform decision-making across the school. To do so, they developed interim assessments that generate actionable data, but the process of mining the data for relevant information was incredibly cumbersome. Expediting and improving the data analysis process, they designed a coherent process for analyzing the data quickly to find the most important information.

This process can now be applied time and time again and has enabled them to tailor instructional planning to the needs of students. Computational Thinking for Journalism To measure gender stereotypes in films, Julia Silge, data scientist and author of Text Mining with Rcoalesced data from movie scripts.

Decomposing the problem, she specified that she would specifically look at the verb association with male and female pronouns in screen direction. By identifying patterns in sentence structure, Silge was able to measure and abstract data from these on a mass scale, which made the research possible. Algorithmic thinking is a derivative of computer science and coding. This approach automates the problem-solving process by creating a series of systematic logical steps that process a defined set of inputs and produce a defined set of outputs based on these.

Algorithmic thinking is not solving for a specific answer; instead, it solves how to build a replicable process — an algorithm, which is a formula for calculating answers, processing data, or automating tasks.

Algorithmic Thinking Examples If you are like me, examples can help conceptualize how algorithms operate and what they are capable of doing.

Algorithmic Thinking in Long Division Without having to dive into technology, there are algorithms we teach students, whether or not we realize it. For example, long division follows the standard division algorithm for dividing multi-digit integers to calculate the quotient.

The division algorithm enables both people and computers to solve division problems with a systematic set of logical steps, which this video shows.

Rather than having to analyze and parse through these problems, we are able automate solving for quotients because of the algorithm.

Algorithmic Thinking in Standardized Testing A somewhat recent development in standardized testing is the advent of computer adaptive assessments that pick questions based on student ability as determined by correct and incorrect answers given. If students select the correct answer to a question, then the next question would be moderately more difficult.

But if they answer wrong, then the assessment offers a moderately easier question. This occurs through an iterative algorithm that starts with a pool of questions. After an answer, the pool is adjusted accordingly. This repeats continuously. The purpose of this algorithmic approach to assessment is to measure student performance in a more targeted way.

Some problems are one-offs.

You solve them, apply the solution and move on. Algorithmic thinking needs to kick in when similar problems have to be solved over and over again. You don't want to have to think it through anew every time.

You want a solution that works every time. Algorithmic thinking is important for many "strategy" board games. Ideally you want to come up with a strategy that is guaranteed to win, or at least never lose. All such a strategy is is a set of rules that tell you what to do at each step without thinking: what computer scientists call an algorithm.

If you can create such a set of rules, not only could it be the basis of you playing well, but also of a computer program that plays well.

Even your granny or kid brother should be able to play a perfect game by following your rules! Algorithmic thinking is the ability to think in terms of such algorithms as a way of solving problems. It is a core skill people develop when they learn to write their own computer programs. Do some algorithmic thinking of your own: Win at Noughts and Crosses.
