The Fibonacci Sequence. var pop = prompt ("Enter the count of values in the series", " "); var var1=0, var2=1; document.write ("Here is the fibonacci series : "); document.write ("",var1," "); document.write ("",var2," "); var counter, sum; for (counter=2; counter 1, it should return F n-1 + F n-2. This series focuses on learning and practicing JavaScript. Given a number N return the index value of the Fibonacci sequence, where the sequence is: After a quick look, you can easily notice that the pattern of the sequence is that each value is the sum of the 2 previous values, that means that for N=5 → 2+3 or in maths: The Fibonacci sequence appears in nature all around us, in the arrangement of seeds in a sunflower and the spiral of a nautilus for example. A Fibonacci sequence is one where every element is a sum of the previous two elements in the sequence. * We must know the value of two consecutive elements to calculate the value of the next element in the sequence (i.e., )..* fibonacci(n)=fibonacci(n-1)+fibonacci(n-2) if n>1 * fibonacci(n==0)=0 * fibonacci(n==1)=1 * Thus, we consider the base case to be when we reach the first two elements of the series. Fibonacci Series is a series of numbers where the first two Fibonacci numbers are 0 and 1, and each subsequent number is the sum of the previous two. After these first two elements, each subsequent element is equal to the sum of the previous two elements. hackkerrank hackerrank-solutions hackerrank-algorithms-solutions hackerrank-challenges hackerrank-javascript problem-solving problemsolving es6 solutions leetcode-solutions leetcode algorithms cracking-the-coding-interview es5 datastructures challenges-solved topcoder computer-science software-engineering This series focuses on learning and practicing JavaScript. inp = int(input()) cube = lambda x: x**3 # complete the lambda function def fibonacci(n): a,b = 0,1 for i in range(n): yield a a,b = b,a+b print(list(map(cube, list(fibonacci(inp))))) Norman99 4 years ago.
