你正在和你的朋友玩猜数字(Bulls and Cows)游戏:你写下一个数字让你的朋友猜.每次他猜测后,你给他一个提示,告诉他有多少位数字和确切位置都猜对了(称为”Bulls“, 公牛),有多少位数字猜对了但是位置不对(称为“Cows“, 奶牛).你的朋友将会根据提示继续猜,直到猜出秘密数字.举个例子:秘密数字:  "1807"朋友猜的数字: "7810"提示:1 公牛和 3 奶牛.(那个公牛是8,奶牛是0, 1 和7.)请写出一个根据秘密数字和朋友的猜测返回提示的…

Example 1: Input: secret = "1807", guess = "7810" Output: "1A3B" Explanation: 1 bull and 3 cows. The bull is 8, the cows are 0, 1 and 7. Example 2: Input: secret = "1123", guess = "0111" Output: "1A1B…

Question 299. Bulls and Cows Solution 题目大意:有一串隐藏的号码,另一个人会猜一串号码(数目相同),如果号码数字与位置都对了,给一个bull,数字对但位置不对给一个cow,注:数字对与位置对优先,一个号码不能重复判断. 思路:构造map结构,遍历实现 Java实现:实现的不漂亮,好歹能通过 public String getHint(String secret, String guess) { Map<Character, Index> map = new…

A就是统计猜对的同位同字符的个数 B就是统计统计猜对的不同位同字符的个数 非常简单的题 class Solution { public: string getHint(string secret, string guess) { , cntB = ; ] = {}, gn[] = {}; ; i < secret.size(); ++i){ if(secret[i] == guess[i]) cntA++; sn[secret[i]-']++; gn[guess[i]-']++; } ; i<…

#-*- coding: UTF-8 -*-class Solution(object):      def getHint(self, secret, guess):          """         :type secret: str         :type guess: str         :rtype: str         """          countA,i,numList=0,-1,[[0,0] for j…

class Solution(object):    def getHint(self, secret, guess):        """        :type secret: str        :type guess: str        :rtype: str        """        countA,i,numList=0,-1,[[0,0] for i in range(10)]        while True:…

题意: 给出两个数字,输出(1)有多少位是相同的(2)有多少位不在正确的位置上. 思路: 扫一遍,统计相同的,并且将两串中不同的数的出现次数分别统计起来,取小者之和就是第2个答案了. class Solution { public: string getHint(string secret, string guess) { ; ,sizeof(int)*N); ,sizeof(int)*N); , wrong=; ; i<secret.size(); i++) { if(secret[i]==g…

题意:... 析:随机判断就即可,每次把不正确的删除,经过几次后就基本剩不下了. 代码如下: #pragma comment(linker, "/STACK:1024000000,1024000000") #include <cstdio> #include <string> #include <cstdlib> #include <cmath> #include <iostream> #include <cstring…

[链接] 我是链接,点我呀:) [题意] 给你一个长度为4的数字序列(每个数字都在0~9之间,且不重复出现) 现在让你猜这个长度为4的序列是什么. 猜了之后对方会告诉有几个数字是位置和数字都正确的(猜的数字序列有顺序) 以及有几个数字是数字出现了但是位置不正确. 即给你两个反馈. 现在给你n个猜的过程(猜的4个数字以及对应的两个反馈) 问你是否能唯一的确定一个4位数字的答案 [题解] 列举出来最后的4位数的所有可能. 对于每一种可能 将其对这n个猜的过程验证一遍> 如果验证通过,那么递增sum…

题目如下: 解题思路:本题难度不太大,对时间复杂度也没有很高的要求.我的做法是用一个字典来保存每个字符出现的次数,用正数1记录标记secret中出现的字符,用负数1记录guess中出现的字符,这样每出现一次正负抵消,即表示出现了一次cow. 代码如下: class Solution(object): def getHint(self, secret, guess): """ :type secret: str :type guess: str :rtype: str &quo…

public String getHint(String secret, String guess) { /* 判断bull 是通过比较两个字符串的每一位,每次相同就删除该字符出现的次数,因为后边的 要判断cow不能占用这些 判断cow只要检测出去被占用的还有没有该字符 */ //key记录字符,value记录出现的次数 Map<Character,Integer> map = new HashMap<>(); String res = ""; int a =…
