发帖标记一下,我和总榜上有名的专家还有很大距离,我只是程序刚入门,要向他们学习 ~ 同时也希望通过努力缩小与他们的差距.

虽说很久前回帖 就不敢"胡说八道"了,是经过认真思索后给出答案,但有时还是会有偏差,以下这句话用来给自己提醒吧
"除了那些无聊的UP/GZ回贴外，功利性现象越来越严重，不懂装懂的回帖也越来越多。虽然这些回帖的初始愿望大概是好的，但误导别人，即使是无意的，也总是不太好吧，难道大家都没学过孔夫子的话“知之为知之，不知为不知，是知也”么？"saucer
是谁说的我就不多说了,不是我要卖关子 是因为如果你连他都不知道的话,那真白在CSDN混了.
答题要时常告诫自己,责任才是最重要的.可能因为短短的一行错误的或有潜在BUG的回答,初学者要花费很长时间才能够改正.
这并不是我希望看到的,所以一定要避免这类情况发生.
同时也和初学者说一句话,扎实的基础才是最重要的,勿在浮沙筑高台.
最后分享一段小程序,求字符串中出现最多的字符和出现的次数
- C# code
class Program { private const string PromptString = "Please enter a string :"; private const string ConfirmPromptString = "Your enter the string is : \"{0}\""; private const string TabString = "\t\t\t"; private const string FrequencyString = "The highest frequency in enter string is character '{0}',count is {1}"; static void Main(string[] args) { while (true) { Console.WriteLine(PromptString); Console.WriteLine(); Console.Write(TabString); string enterString = Console.ReadLine(); Console.WriteLine(); Console.WriteLine(ConfirmPromptString, enterString); Console.WriteLine(); char highestFrequencyChar; int count; MethodOne(enterString, out highestFrequencyChar, out count); Console.WriteLine("MethodOne :"); Console.WriteLine(); Console.WriteLine(FrequencyString, highestFrequencyChar, count); Console.WriteLine(); MethodTwo(enterString, out highestFrequencyChar, out count); Console.WriteLine("MethodTwo :"); Console.WriteLine(); Console.WriteLine(FrequencyString, highestFrequencyChar, count); Console.WriteLine(); } } private static int MethodOne(string enterString, out char highestFrequencyChar, out int count) { IDictionary<char, int> dic = new Dictionary<char, int>(); highestFrequencyChar = ' '; int max = 0; for (int i = 0, len = enterString.Length; i < len; i++) { if (dic.TryGetValue(enterString[i], out count)) { if (++dic[enterString[i]] > max) { max = dic[enterString[i]]; highestFrequencyChar = enterString[i]; } } else { dic[enterString[i]] = 1; } } count = max; return 1; } private static int MethodTwo(string enterString, out char highestFrequencyChar, out int count) { highestFrequencyChar = ' '; count = 0; int tempCount; for (int i = 0, len = enterString.Length; i < len; i++) { if ((tempCount = len - enterString.Replace(enterString[i].ToString(), "").Length) > count) { count = tempCount; highestFrequencyChar = enterString[i]; } } return 1; } }------解决方案--------------------
