Remove the first and last character of each word in a string

Last Updated : 25 Sep, 2022

Given the string the task is to remove the first and last character of each word in a string.
Examples:

Input: Geeks for geeks
Output: eek o eek

Input: Geeksforgeeks is best
Output: eeksforgeek es

Approach :

Split the String based on the space
Run a loop from the first letter to the last letter.
Check if the character is the starting or end of the word
Remove this character from the String.

Below is the implementation of the above approach.

C++

// C++ program to remove the first 
// and last character of each word in a string. 
#include<bits/stdc++.h>
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<str.length();i++)
    {
        if(str[i]==' ')
        {
            // excluding the first and 
            // last character
            res +=w.substr(1,w.length()-2)+" "; 
                
            // clear the word
            w="";
        }
        else
        {
            // else add the character to word
            w+=str[i];
        }
    }

    return res; 
} 

// Driver code 
int main()
{ 
    string str = "Geeks for Geeks"; 
    cout << (str) << endl; 
    cout << FirstAndLast(str) << endl;
    return 0;
}

Java

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));
    }
}

        str += " ";

        var res = "",
          w = "";

        // 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) + " ";

      // Driver code
      var str = "Geeks for Geeks";
      document.write(str + "<br>");
      document.write(FirstAndLast(str) + "<br>");
      
</script>

Output:

Geeks for Geeks
eek o eek

Time complexity: O(n) where n is the length of the given string
Auxiliary space: O(n) because using extra space for string res and string w.
