1/8/2024 0 Comments Python fibFibonacci series in python using dynamic programmingĭynamic Programming is an algorithmic technique that solves problems by breaking them into subproblems and saves the result of these subproblems so that we do not have to re-compute them when needed. So, it’s better to avoid this recursive approach in the Fibonacci series program. Now we have to calculate for the last two values that is fib(7-1) + fib(7-2), which is fib(6) + fib(5), but when we calculate for fib(6), again fib(5) will be calculated as you can see in the below diagram. Suppose we have passed n = 7 to our function fib(7). Space Complexity: O(n) (Max depth of the recursion tree) This means our program has calculated the same thing many times, which consumes too much time & space So here, term 7 is called x7, which is equal to 13,įrom the above diagram we can write the formula as: Xn = Xn-1 + Xn-2įrom the diagram below, we can see there is a lot of repetition of the functions. Now the last two numbers are (1,2), we add them to get the following number of the Fibonacci series, and It is done until the number of terms you want. The following number will be an addition of the last two numbers.Īs you can see in the above diagram, The Fibonacci series started with 0 and 1 currently, which are the last two numbers and then by adding these values, we got 1. Fibonacci Series Logic in Pythonįibonacci series starts with 0 and 1, so we consider these as the default values of the series. We can define the Fibonacci series as a series of numbers that start from 0 & 1, and the next number can be generated by adding the last two preceding numbers. The following are the first few values in the sequence, starting with 0 and 1 : 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144. The series usually begins with 0 and 1, while some authors skip the first two terms and begin with 1 and 1 or 1 and 2. The Fibonacci numbers, abbreviated as Fn in mathematics, comprise a Fibonacci sequence in which each number is the sum of the two preceding ones.
