算法与程序设计

1. 问题1:

如下图所示算法，输出结果是 ________________________。

1.1. Python 代码

def question_1():
    a = 0
    b = 1
    while b <= 20:
        a = a + b
        b = b + a

    print(a)
    # print(b)

if __name__=="__main__":
    question_1()

2. 问题2:

如下图所示算法，或输入x=3，输出结果是 ________________________。

2.1. Python 代码

def question_2():
    print("Please enter x = ")
    x = int(input())
    i = 0
    m = 0
    k = 1
    while i < 5:
        if i > 2:
            k = k + x
        else:
            m = m + k
        i = i + 1
        k = k + 1

    print("k= %d" % k)
    print("m= %d" % m)


if __name__=="__main__":
    question_2()

3. 问题3:

如下图所示算法，输出结果是 ________________________。

3.1. Python 代码

def question_3():
    i = 1
    s = 1
    while (True):
        s = s * i
        i = i + 3
        if i > 100:
            break

    print("s= %d" % s)
    print("i= %d" % i)    

if __name__=="__main__":
    question_3()
