Unidirectional hash is a function that transforms a variable length string into a fixed length output,and the output value is called a hash value.The hash function is public.The hash function can only be calculated from one direction,without trap door,but only calculates the hash value of a message to determine whether the message has been tampered with.For example,we use H(m)=S to indicate that we use a one-way hash function to calculate the message m and get the hash value S,but we cannot deduce what the message m is from S.If I send the message m and S to you together,you use the same hash function to calculate m,and if the hash obtained is equal to S,it means that the message you receive is the same as my original message and has not been intercepted or tampered with halfway. 　　以下是一個簡單的哈希競猜游戲的邏輯代碼示例。這個游戲中，玩家需要猜測一個數(shù)，游戲會根據(jù)玩家的猜測返回一個提示信息，提示玩家猜測的數(shù)字是比目標數(shù)字大還是小。游戲會根據(jù)玩家的猜測次數(shù)進行統(tǒng)計，并在最后顯示出猜測次數(shù)最多的數(shù)字。注意I80流程2857技術(shù)8624過程!它也是的概念，

　　```python 　　import random 　　def create_num(lower_bound,upper_bound): 　　return random.randint(lower_bound,upper_bound) 　　def main(): 　　lower_bound=1 　　upper_bound=100 　　num_played=0 　　while True: 　　user_input=input("請輸入一個1到100之間的整數(shù)（輸入q退出游戲）：") 　　if user_input.lower()=="q": 　　break 　　num=int(user_input) 　　if num>upper_bound or num<lower_bound: 　　print("輸入的數(shù)字不在1到100之間，請重新輸入。") 　　continue 　　played_times=num-create_num(lower_bound,upper_bound) 　　print(f"{num}次猜測，最大猜測數(shù)字為{create_num(lower_bound,upper_bound)}。") 　　num_played+=1 　　if num_played>played_times: 　　print("最大猜測數(shù)字為{create_num(lower_bound,upper_bound)}。") 　　if __name__=="__main__": 　　main() 　　``` 　　請注意，這個示例代碼僅作為參考，您可以根據(jù)自己的需求對其進行修改和擴展。
