def __main__():
a, b, n, x1, xn = input().split()
a = float(a)
b = float(b)
n = int(n)
x1 = float(x1)
xn = float(xn)
kb = [(0, x1) for i in range(n)]
kb[1] = (1, 0)
for i in range(2, n):
kb[i] = (a * kb[i - 1][0] + b * kb[i - 2][0], a * kb[i - 1][1] + b * kb[i - 2][1])
x2 = (xn - kb[-1][1]) / kb[-1][0]
print(x1)
print(x2)
for i in range(2, n):
t = a * x2 + b * x1
x1 = x2
x2 = t
print(t)
__main__()
这程序好像有点Bug，我给组数据试试？
