Java Recursion FAQs
The base case, also known as the termination condition, is the simplest scenario that can be directly solved without further recursion. It is a critical part of a recursive function, as it prevents infinite recursion and allows the recursion to terminate correctly.
Direct recursion occurs when a function calls itself directly, whereas indirect recursion occurs when a function calls another function, which, in turn, calls the original function or some other function that eventually calls the original function again.
Recursion is suitable for problems that exhibit a recursive structure, such as traversing trees, graphs, or recursive mathematical calculations (e.g., factorial or Fibonacci). It can also be used for problems that can be divided into smaller subproblems.
Debugging recursive functions can be challenging due to their complex nature. Using print statements to trace the function calls and their arguments can be helpful. Additionally, using a debugger with step-by-step execution can aid in understanding the recursive process.
