我在Project Euler上的问题2遇到了麻烦.目标是找到Fibonacci序列中偶数值的总和,其值不超过四百万.由于某种原因,我一直得到0作为我的输出.我究竟做错了什么？
total = 0
count = 0
term = 0
fibonacciMemo = {0:0, 1:1}
def main ():
term = fibonacci (count)
while (term <= 4000000):
if (term % 2 == 0):
total += term
count += 1
def fibonacci (n):
if not n in fibonacciMemo:
fibonacciMemo [n] = fibonacci (n - 1) + fibonacci (n - 2)
return fibonacciMemo [n]
print (total)
