8 recursion practice problems mixing Java and Python, the topic most CS students find hardest to click. Covers base cases, the call stack, and memoization through problems that build from simple (digit sum, factorial) to genuinely useful (memoized Fibonacci, recursive binary search, Euclid's GCD).

Each problem includes a clear prompt, starter code with blanks to fill in, expected output, a full working solution, and a plain-language explanation of why the recursion works, not just what the code does.

What's included:
• 8 recursion problems across Java and Python
• Progressive difficulty, from digit sum to recursive binary search
• Full answer key with explanations of the call stack behaviour
• Rubric per problem (K/A/C/T categories)
• Print-ready PDF, A4 format, student + answer key pages

Perfect for ICS4U/AP CS A students hitting recursion for the first time, or anyone brushing up before a data structures course. Instant download.
