Python |删除给定句子中的所有重复单词-yiteyi-C++库

给定一个包含n个单词/字符串的句子。删除所有相互相似的重复单词/字符串。例如：

null

Input : Geeks for GeeksOutput : Geeks forInput : Python is great and Java is also greatOutput : is also Java Python and great

推荐：请尝试你的方法 {IDE} 首先，在进入解决方案之前。

我们可以使用 python Counter（）方法 .方法非常简单。 1）将空格分隔的输入句子拆分为单词。 2）所以，为了首先把所有这些字符串放在一起，我们将把每个字符串加入到给定的字符串列表中。 3）现在使用计数器方法创建一个字典，字符串作为键，频率作为值。 4）连接每个单词都是唯一的，形成一个字符串。

方法3： 另一个较短的实现：

Python3

                         # Python3 program
