Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Create a Python function using a nested function that computes the total salary given a basic salary and HRA, where HRA is calculated as a percentage of the basic.

💡 Hint: Consider how the nested function can directly access the outer function's variable.

Challenge 2 Hard

Explain how the closure you created can be applied to maintain state across multiple function calls, using a Python implementation.

💡 Hint: Draw parallels with practical instances where keeping a state is needed, like tracking scores in a game.
