# Write an algorithm for fibonacci series using recursion

Try to figure it out on your own, then come back with the code if you can't do it. Origins[ edit ] Thirteen ways of arranging long and short syllables in a cadence of length six. Five end with a long syllable and eight end with a short syllable. A page of Fibonacci 's Liber Abaci from the Biblioteca Nazionale di Firenze showing in box on right the Fibonacci sequence with the position in the sequence labeled in Latin and Roman numerals and the value in Hindu-Arabic numerals.

The Fibonacci sequence appears in Indian mathematicsin connection with Sanskrit prosody. Counting the different patterns of successive L and S with a given total duration results in the Fibonacci numbers: He dates Pingala before BC.

Variations of two earlier meters [is the variation] For example, for [a meter of length] four, variations of meters of two [and] three being mixed, five happens. Fibonacci posed the puzzle: At the end of the first month, they mate, but there is still only 1 pair. At the end of the second month the female produces a new pair, so now there are 2 pairs of rabbits in the field. At the end of the third month, the original female produces a second pair, making 3 pairs in all in the field.

At the end of the fourth month, the original female has produced yet another new pair, and the female born two months ago also produces her first pair, making 5 pairs. This is the nth Fibonacci number.Output. Time Complexity: T(n) = T(n-1) + T(n-2) which is exponential.

We can observe that this implementation does a lot of repeated work (see the following recursion tree). So this is a bad implementation for nth Fibonacci number. Possible Duplicate: Recursion and Iteration What is the difference between a recursive and a non-recursive function? Fibonacci to be exact.

I looking for answers that relate towards the time. In Fibonacci series, each term is the sum of the two preceding terms. The C and C++ program for Fibonacci series using recursion is given below.

## Fibonacci Series Algorithm and Flowchart | Code with C

In mathematics, the Fibonacci numbers or Fibonacci series or Fibonacci sequence are the numbers in the following integer sequence: By definition, the first two numbers in the Fibonacci sequence are 0 and 1, and each subsequent number is the sum of the previous two.

Fibonacci series is defined as a sequence of numbers in which the first two numbers are 1 and 1, or 0 and 1, depending on the selected beginning point of the sequence, and each subsequent number is the sum of the previous two. Data structures and algorithm questions are an important part of any programming job interview, be it a Java interview, C++ interview or any other programming language.
