You are optimizing a recursive algorithm for a real-time system where function call overhead is a critical concern. What strategy might be most effective in reducing the function call overhead while maintaining the logical structure of the algorithm? 

  • Use inline functions. 
  • Optimize the algorithm's base cases. 
  • Introduce parallel processing. 
  • Rely on external libraries.
Function call overhead is the extra time and resources needed when a function is called. Using inline functions can help reduce this overhead, especially in recursive algorithms, because the function's code gets inserted (or "inlined") at each point where the function is called, eliminating the need for the typical call and return process, which can be resource-intensive.
