๐งฉ Problem statement
Track spending by category and date, with totals and the biggest expense. Design it completely in pseudocode first: plan the data, split the work into functions, write the logic, dry-run it and test it.
๐ Requirements
- Add expense
- Category
- Date
- Total

๐ง Constraints
- Dates written as YYYY-MM-DD
๐งญ Suggested approach
- Restate the problem in your own words
- List the data you must remember (variables, lists, maps)
- Write one FUNCTION per feature
- Write the main program that calls them
- Dry-run with the Run button
- Test normal cases and edge cases
๐ง Required concepts
- Functions
- Lists
- Maps
- Searching
- Sorting
โ๏ธ Pseudocode editor ยท dry-run tool ยท test cases
