Study Notes

Problem-Solving Approach

Identify the problem and define it clearly to understand the requirements and constraints
Identify the inputs and desired outputs to clarify the problem's scope

Decomposition

Break down the problem into smaller, more manageable parts to simplify the solution
Solve each part individually before combining them to ensure a comprehensive solution

Pattern Recognition

Identify patterns or similarities to previously solved problems to adapt known solutions
Use known solutions and adapt them to the current problem to leverage existing knowledge

Abstraction

Focus on the important information only, ignoring irrelevant details to simplify the problem
Use models or representations to simplify the problem and highlight key aspects

Algorithm Design

Develop a step-by-step solution using pseudocode or flowcharts to visualize the process
Consider different approaches (e.g., brute force, divide and conquer, greedy algorithms, dynamic programming) to choose the best solution

Implementation

Translate the algorithm into a programming language to create a working solution
Use appropriate data structures and control structures to ensure efficient execution

Testing and Debugging

Test the solution with different inputs to ensure correctness and identify errors
Identify and fix any errors or bugs to refine the solution

Optimization

Improve the efficiency of the solution by refining the algorithm
Refine the algorithm to reduce time and space complexity to ensure optimal performance
