python求和

We are going to design a special sum series function which has following characteristics:

我們將設(shè)計(jì)一個(gè)特殊的求和系列函數(shù)，該函數(shù)具有以下特征：

f(0) = 0f(1) = 1f(2) = 1f(3) = 0f(x) = f(x-1) + f(x-3)

Python solution of the above sum series

上述sum系列的Python解決方案

# function to find the sum of the series def summ(x):if x == 0:return 0if x == 1:return 1if x == 2:return 1if x == 3:return 0else:return summ(x-1) + summ(x-4)# main code if __name__ == '__main__':# finding the sum of the series till given value of xprint("summ(0) :", summ(0))print("summ(1) :", summ(1))print("summ(2) :", summ(2))print("summ(3) :", summ(3))print("summ(10):", summ(10))print("summ(14):", summ(14))

Output

輸出量

summ(0) : 0 summ(1) : 1 summ(2) : 1 summ(3) : 0 summ(10): 5 summ(14): 17
