CodePath Intermediate Group 46 Problems
Best practices:
- Make your own branches from main, and name the branch something sensible and easily identifiable (ie: kevc, tphan, xhuang etc.).
- Use the pull request feature, someone else from the group will need to merge the changes into the main branch.
- Solutions will need to include your steps following the UMPIRE problem solving steps.
UMPIRE
- Understand what the interviewer is asking for by using test cases and questions about the problem.
- Match what this problem looks like to known categories of problems, e.g. Linked List or Dynamic Programming and strategies or patterns in those categories.
- Plan the solution with appropriate visualizations and pseudocode.
- Implement the code to solve the algorithm.
- Review the code by running specific example(s) and recording values (watchlist) of your code's variables along the way.
- Evaluate the performance of your algorithm and state any strong/weak or future potential work.
Example:
"""
Prompt - Write a function to determine if a given value is even or odd.
Understand:
* Should this problem be solved with math?
* Are the given values only greater than zero?
Match:
* Math, Binary representation
Plan:
* Write a function that uses modulo 2 to evaluate value
Implement:
* Written solution below.
Review:
* value=2 -> True
* value=3 -> False
Evaluate:
* Time complexity - O(1) because mathematical operations are done with bitshifting techniques
* Space complexity - O(1) because no additional space is used to evaluate a given value.
