好久没切 leetcode 的题了,静下心来切了道,这道题比较有意思,和大家分享下. 我把它叫做 "不一样的猜数字游戏",我们先来看看传统的猜数字游戏,Guess Number Higher or Lower.题意非常的简单,给定一个数字 n,系统会随机从 1 到 n 中抽取一个数字,你需要写一个函数 guessNumber,它的作用是返回系统选择的数字,同时你还有一个外部的 API 可以调用,是为 guess 函数,它会将你猜的数字和系统选择的数字比较,是大了还是小了. 非常的简单,…

原题 思路: miniMax+DP dp[i][j]保存在i到j范围内,猜中这个数字需要花费的最少 money. "至少需要的花费",就要我们 "做最坏的打算,尽最大的努力",即取最大值. dp[beg][end] =MIN ( i + max(helper(beg, i - 1, dp), helper(i + 1, end, dp)) ) class Solution { public: int helper(int beg, int end, vector&l…

Leetcode之二分法专题-374. 猜数字大小(374. Guess Number Higher or Lower) 我们正在玩一个猜数字游戏. 游戏规则如下:我从 1 到 n 选择一个数字. 你需要猜我选择了哪个数字.每次你猜错了,我会告诉你这个数字是大了还是小了.你调用一个预先定义好的接口 guess(int num),它会返回 3 个可能的结果(-1,1 或 0): -1 : 我的数字比较小 1 : 我的数字比较大 0 : 恭喜!你猜对了! 示例 : 输入: n = 10, pick…

我们正在玩一个猜数游戏,游戏规则如下:我从 1 到 n 之间选择一个数字,你来猜我选了哪个数字.每次你猜错了,我都会告诉你,我选的数字比你的大了或者小了.然而,当你猜了数字 x 并且猜错了的时候,你需要支付金额为 x 的现金.直到你猜到我选的数字,你才算赢得了这个游戏.示例:n = 10, 我选择了8.第一轮: 你猜我选择的数字是5,我会告诉你,我的数字更大一些,然后你需要支付5块.第二轮: 你猜是7,我告诉你,我的数字更大一些,你支付7块.第三轮: 你猜是9,我告诉你,我的数字更小一些,你支付…

最后更新 四刷? 极大极小算法..还是叫极小极大的.. 首先要看怎么能保证赢. 比如2个数,猜第一个猜第二个都能保证下一轮我们赢定了,为了少交钱,我们猜小的. 比如3个数,猜第二个才能保证下一轮再猜一定能赢. 比如4个数,怎么猜都不能保证下一轮一定赢,所以要猜两轮.第一轮猜1,2,3还是4就很讲究了. 猜1就是num1 + dp[2][4](今后花费) 猜2就是dp[1][1](今后花费) + num2或者num[1] + dp[3][4](今后花费) ... 4种里每种都算出来,看哪种花费最少…

想当年高中时经常和小伙伴在纸上或者黑板上或者学习机上玩猜数字的游戏,在当年那个手机等娱乐设备在我们那还不是很普遍的时候是很好的一个消遣的游戏,去年的时候便写了一个Android版的猜数字游戏,只是当时没写完,最近又拿出来改了一下,完善了一些功能,修正了很多bug,终于将V0.1版做了出来,现贴出来分享一下. 鉴于居然有很多人都不会玩这个游戏,我还是简单介绍下规则吧: 猜数字: 系统每次随机产生一个4位数字,4位数的每一位都不相同,且都为0~9,然后你有5次机会去猜出那个数字,每次你猜一个4位数,…

--------------------------------------------------------------- V0.1版本 上次做完第一个版本后,发现还有一些漏洞,并且还有一些可以添加的功能,以及一些可改进的地方,于是准备继续完善此游戏,顺便学Android了. 本次更新信息如下: 1.改正了随机数生成算法,更正了不能产生数字'9'的bug 2.增加了数据存储与IO的内容,使用了SharedPreferences保存数据 3.保存数据为: 总盘数,猜中的盘数 4.使用了Simp…

最近学习了MFC一些比较基础的知识,所以打算通过做一个简单的数字游戏来理解MFC的流程并进一步熟悉其操作. 在这里,我做了一个猜数字的小游戏.第一步当然是设计主界面,先给大家展示一下游戏界面: 主界面: 从这个主界面可以看到,它包含标题,菜单栏,工具栏. 标题是给人一个认识,这是什么游戏,标题设置为:“猜数游戏”: 而菜单栏和工具栏才是游戏的核心,它要保证能够完成游戏的基本功能. 菜单栏和工具栏是对应的,包含了”start“,"help","restart"这三个菜…

猜数字游戏 猜数字游戏是以前功能机上的一款益智游戏,计算机会根据输入的位数随机分配一个符合要求的数据,计算机输出guess后便可以输入数字,注意数字间需要用空格或回车符加以区分,计算机会根据输入信息给出相应的提示信息:A表示位置与数字均正确的个数,B表示位置不正确但数字争取的个数,这样便可以根据提示输入,直到正确为止,并且根据输入次数给出相应评价. 源代码如下: #include<stdio.h> #include<time.h> #include<stdlib.h>…
