Java Programming: Solving Problems with Software

The assignments from Java Programming: Solving Problems with Software on Coursera

Solving Programming Problems: A Seven Step Approach

1. Work Example By Hand

• Solve small instance by hand
• Unclear problem?
• Need domain knowledge?

2. Write Down What You Did

• Write down exact steps
• Just that instance
• Tricky: do without thinking

3. Find Patterns

• Algorithm for any instance
• Find patterns
• Repetition, conditions, values
• Difficulties?
  • Try step 1 + 2 again
  • Different inputs

4. Check By Hand

• Incorrect pattern? Find now
• Check with different inputs

5. Translating To Code

• Programming language

6. Run Test Cases

• Run test cases on code
• Check anwser

7. Debug Failed Test Cases

• Test failed? Debug
  • Use scientific method
  • Understand problem + fix
• Algorithm problem?
  • Return to step 3 and fix the algorithm
• Implementation problem?
  • Return to step 5 and correct the translation of the algorithm to code
