What is the time complexity of recursion?
The time complexity of recursion depends on the specific algorithm. Can you provide an example?
Sure! What about the Fibonacci sequence?
The naive recursive solution for Fibonacci has an exponential time complexity of O(2^n). This is due to repeated calculations.
Is there a more efficient way to calculate Fibonacci?
Yes! Using dynamic programming or memoization can reduce the time complexity to O(n). Would you like to see an example?
