Remove the first and last character of each word in a string
  • Difficulty Level : Easy
  • Last Updated : 06 May, 2021

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

// 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));
    }
}

Python3




# Python3 program to remove the first
# and last character of each word in a string.
 
def FirstAndLast(string) :
     
    # Split the String based on the space
    arrOfStr = string.split();
 
    # String to store the resultant String
    res = "";
 
    # Traverse the words and
    # remove the first and last letter
    for a in arrOfStr :
        res += a[1:len(a) - 1] + " ";
     
    return res;
     
# Driver code
if __name__ == "__main__" :
     
    string = "Geeks for Geeks";
     
    print(string);
    print(FirstAndLast(string));
