Thank you, you are really a genius.
Very helpful indeed.You explain a lot better than professor and it really helped me figure out how does this actually work. +1
Sir, THANK YOU VERY MUCH!! it's not only in knowing something but in the ability to explain it! great video!
#C++ lols This 8mins video explains more than 2hrs of my professor ever did Stepping Through Recursive Fibonacci Function
Hi! How can I calculate the number of recursive calls for the n-th fibonacci term when the n tends to get really high? And just so I'm clear, I'm not interested in the n-th term itself, but rather the number of recursive calls only. Thanks in advance!
Just did this… The counter goes into the billions by fibonacci(43).
What you could do is declare a static int as a counter and increment it somewhere in your recursive function. Since it's a static variable it will remember its value through all of the calls. After the final call, the value of your counter variable should be the number of recursive calls. I haven't tested this so I don't know the exact implementation.
very nice explaination thank u very much
