编写代码利用顺序栈将二进制转八进制，十进制，十六进制

以下是使用顺序栈实现二进制转八进制、十进制、十六进制的代码：

class Stack:
    def __init__(self):
        self.items = []

    def is_empty(self):
        return len(self.items) == 0

    def push(self, item):
        self.items.append(item)

    def pop(self):
        return self.items.pop()

    def peek(self):
        return self.items[-1]

    def size(self):
        return len(self.items)

def binary_to_decimal(binary):
    decimal = 0
    index = 0
    for i in range(len(binary)-1, -1, -1):
        decimal += int(binary[i]) * 2**index
        index += 1
    return decimal

def decimal_to_octal(decimal):
    octal = Stack()
    while decimal > 0:
        remainder = decimal % 8
        octal.push(str(remainder))
        decimal //= 8
    result = ''
    while not octal.is_empty():
        result += octal.pop()
    return result

def decimal_to_hexadecimal(decimal):
    hexadecimal = Stack()
    while decimal > 0:
        remainder = decimal % 16
        if remainder < 10:
            hexadecimal.push(str(remainder))
        else:
            hexadecimal.push(chr(ord('A') + remainder - 10))
        decimal //= 16
    result = ''
    while not hexadecimal.is_empty():
        result += hexadecimal.pop()
    return result

if __name__ == '__main__':
    binary = input('请输入二进制数：')
    decimal = binary_to_decimal(binary)
    print(f'转换为十进制：{decimal}')
    octal = decimal_to_octal(decimal)
    print(f'转换为八进制：{octal}')
    hexadecimal = decimal_to_hexadecimal(decimal)
    print(f'转换为十六进制：{hexadecimal}')

运行结果：

请输入二进制数：1011101
转换为十进制：93
转换为八进制：135
转换为十六进制：5D
