Janelle is going to write an algorithm. Which of the following should she do first?
(1 point)
make a plan
carry out the plan
extend the problem
understand the problem
Janelle should first understand the problem.
Janelle should first understand the problem.
To determine which step Janelle should do first, we need to understand the process of writing an algorithm. An algorithm is a step-by-step procedure to solve a problem or accomplish a specific task. In this case, Janelle is going to write an algorithm.
The first step she should take is to "understand the problem." It is important to have a clear understanding of the problem or task before attempting to solve it. This involves analyzing the problem, identifying the requirements, constraints, and desired outcomes. It helps Janelle to define the problem and gain insight into what needs to be achieved.
Once Janelle has a good understanding of the problem, she can move on to "make a plan." This involves brainstorming possible strategies and approaches to solve the problem. Janelle can consider different algorithms, data structures, and programming techniques that might help in achieving the desired outcome.
After creating a plan, Janelle can proceed to "carry out the plan." This step involves implementing the algorithm using a programming language or other suitable tools. Janelle will write the code based on the plan she has formulated.
Finally, "extend the problem" is not the first step Janelle should take. It comes after carrying out the initial algorithm successfully. Extending the problem refers to adding additional features, enhancements, or modifications to the existing algorithm to handle more complex scenarios or improve its functionality. It is an iterative process that may come into play later, once the initial problem is solved.
Therefore, the correct answer is: Janelle should "understand the problem" first before proceeding with the other steps in the algorithm-writing process.
