删除字符串中每个单词的第一个和最后一个字符

给定字符串，任务是删除字符串。
例子：

Input: Geeks for geeks
Output: eek o eek

Input: Geeksforgeeks is best
Output: eeksforgeek  es

方法

• 根据空间拆分字符串
• 从第一个字母到最后一个字母循环。
• 检查字符是单词的开头还是结尾
• 从字符串中删除此字符。

下面是上述方法的实现。

C++

// C++ program to remove the first
// and last character of each word in a string.
#include
using namespace std;
 
string FirstAndLast(string str)
{
    // add a space to the end of the string
    str+=" ";
         
    string res="",w="";
         
    // traverse the string and extract words
    for(int i=0;i

Java

// and last character of each word in a string.
 
import java.util.*;
 
class GFG {
    static String FirstAndLast(String str)
    {
 
        // Split the String based on the space
        String[] arrOfStr = str.split(" ");
 
        // String to store the resultant String
        String res = "";
 
        // Traverse the words and
        // remove the first and last letter
        for (String a : arrOfStr) {
            res += a.substring(1, a.length() - 1) + " ";
        }
 
        return res;
    }
 
    // Driver code
    public static void main(String args[])
    {
        String str = "Geeks for Geeks";
        System.out.println(str);
        System.out.println(FirstAndLast(str));
    }
}

      function FirstAndLast(str) {
        // add a space to the end of the string
        str += " ";
 
        var res = "",

        // traverse the string and extract words
        for (var i = 0; i < str.length; i++)
        {
          if (str[i] === " ") {
            // excluding the first and
            // last character
 
            res += w.substring(1, w.length - 1) + " ";
 
            // clear the word
            w = "";
          } else {
            // else add the character to word
            w += str[i];
