Day 7: Part 1

Problem Description

The task was to analyze a file system structure and determine the total size of directories that meet specific criteria. The input consists of a representation of the file system, including files and directories.

Approach

To solve this problem, I implemented the following steps:
1. Input Reading: I read the input data from a file, which contains the structure of the file system.
2. Tree Representation: I built a tree representation of the file system, where each node represents a directory or file.
3. Size Calculation: I traversed the tree to calculate the sizes of directories, summing the sizes of their contents.
4. Output: Finally, I printed the total size of the directories that meet the specified criteria.

This approach effectively models the file system and calculates sizes based on the structure.

Key Insights

• Using a tree structure is effective for representing hierarchical data like file systems.
• Recursive traversal can simplify the logic for calculating sizes.

Concepts and Algorithms Used

• Input Handling: Reading from files and processing strings.
• Data Structures: Trees for representing file systems.
• Algorithms: Recursive traversal for size calculation.
