前几天看了一个.net程序员面试题目,题目是”统计给定的文本中字符出现的次数,使用循环和递归两种方法“. 下面是我对这个题目的解法: 1.使用循环: /// <summary> /// 使用For循环统计文本字符串中某一字符出现的次数 /// </summary> /// <param name="c">指定字符</param> /// <param name="text">文本字符串</param&…

.python统计文本中每个单词出现的次数: #coding=utf-8 __author__ = 'zcg' import collections import os with open('abc.txt') as file1:#打开文本文件 str1=file1.read().split(' ')#将文章按照空格划分开 print "原文本:\n %s"% str1 print "\n各单词出现的次数:\n %s" % collections.Counter(s…

1.原题 2.perl脚本 print "================ Method 1=====================\n"; open IN,'<','anna-karenina.txt'; while(<IN>){ chomp; $line = $_; $line =~ s/[ \. , ? ! ; : ' " ( ) { } \[ \]]/ /g; #句号,逗号等统一改为空格 #print("$line\n"); @…

counter是 colletions内的一个类 可以理解为一个简单的计数 import collections str1=['a','a','b','d'] m=collections.Counter(str1) print(m) str2=['你','好','你','你'] m1=collections.Counter(str2) print(m1) 器,可以统计字符出现的个数,例子如下 输出: Counter({'a': 2, 'b': 1, 'd': 1}) Counter({'你':…

思路如下:1.使用的Hashtable(高效)集合,记录每个单词出现的次数2.采用ArrayList对Hashtable中的Keys按字母序排列3.排序使用插入排序(稳定) public void StatisticsWords(string path) { if (!File.Exists(path)) { Console.WriteLine("文件不存在!"); return; } Hashtable ht = new Hashtable(StringComparer.Ordina…

仅简单统计英文. from collections import Counter f = open('1') c = Counter() for line in f: g = (x for x in line.split()) c.update(Counter(g)) f.close() print sorted(dict(c).items(), key = lambda x : x[1], reverse = True) 运行结果. [('cd', 5), ('xy', 2), ('ab',…

1. 要求: 给定一篇纯英文的文本,统计其中回文单词的比列,并输出其中的回文单词,文本数据如下: This is Everyday Grammar. I am Madam Lucija And I am Kaveh. Why the title, Lucija? Well, it is a special word. Madam? Yeah, maybe I should spell it for you forward or backward? I am lost. The word Mada…
