Problem description

Fibonacci numbers, also known as Fibonacci series, refer to such a series: 1, 1, 2, 3, 5, 8, 13, 21, …... This series starts with the third term, and each term is equal to the sum of the first two terms. Find the minimum Fibonacci number that is greater than the input number.

Enter: enter a positive integer n (n > = 10) on one line.

Output: output the minimum Fibonacci number greater than n on one line.

Input sample: 10

Sample output: 13

Solution

The generator, the python language, is used first. Generator definition: a function that uses yield is called a generator. In the process of calling the generator to run, the function pauses and saves all the current running information each time it encounters yield, returns the value of yield, and continues to run from the current location the next time the next () method is executed. Use the generator to get the Fibonacci series, and then display the series as a list. Compare the numbers in the series with the integers entered, filter out the numbers that meet the criteria, and then create a new list to put the numbers that meet the criteria. Finally, print out the first element of the new list, that is, the minimum Fibonacci number that meets the criteria!
