Abbreviate given string by replacing all characters with length except the first and last

Last Updated : 10 Jan, 2022

Given string str, the task is to convert the given string into its abbreviation of the form: first character, number of characters between first and last character, and the last character of the string.

Examples:

Input: str = "internationalization"
Output: i18n
Explanation: First letter 'i', followed by number of letters between 'i' and 'n' i.e. 18, and the last letter 'n'.

Input: str = "geeksforgeeks"
Output: g11s

Approach: The given problem is an implementation based problem that can be solved by following the below steps:

Print the 1st character of the given string str[0].
Store the length of the string in a variable len and print len - 2.
Print the last character of the string i.e, str[len -1].

Below is the implementation of the above approach:

C++

// C++ program of the above approach
#include <iostream>
using namespace std;

// Function to convert the given
// string into its abbreviation
void abbreviateWord(string str)
{
    // Stores the length of the string
    int len = str.size();

    // Print 1st character
    cout << str[0];

    // Print count of characters
    // in between
    cout << len - 2;

    // Print last character
    cout << str[len - 1];
}

// Driver Code
int main()
{
    string str = "internationalization";
    abbreviateWord(str);

    return 0;
}

Java

// Java program for the above approach
import java.util.*;
public class GFG
{
  
  // Function to convert the given
  // string into its abbreviation
  static void abbreviateWord(String str)
  {

    // Stores the length of the string
    int len = str.length();

    // Print 1st character
    System.out.print(str.charAt(0));

    // Print count of characters
    // in between
    System.out.print(len - 2);

    // Print last character
    System.out.print(str.charAt(len - 1));
  }

  // Driver Code
  public static void main(String args[])
  {
    String str = "internationalization";
    abbreviateWord(str);

  }
}

Python3

# Python code for the above approach

# Function to convert the given
# string into its abbreviation
def abbreviateWord(str):

    # Stores the length of the string
    _len = len(str);

    # Print 1st character
    print(str[0], end="");

    # Print count of characters
    # in between
    print(_len - 2, end="");

    # Print last character
    print(str[_len - 1], end="");


# Driver Code
str = "internationalization";
abbreviateWord(str);

// C# program of the above approach
using System;
class GFG
{
  
// Function to convert the given
// string into its abbreviation
static void abbreviateWord(string str)
{
  
    // Stores the length of the string
    int len = str.Length;

    // Print 1st character
    Console.Write(str[0]);

    // Print count of characters
    // in between
    Console.Write(len - 2);

    // Print last character
    Console.Write(str[len - 1]);
}

// Driver Code
public static void Main()
{
    string str = "internationalization";
    abbreviateWord(str);

}
}

JavaScript

  <script>
        // JavaScript code for the above approach

        // Function to convert the given
        // string into its abbreviation
        function abbreviateWord(str)
        {
        
            // Stores the length of the string
            let len = str.length;

            // Print 1st character
            document.write(str[0]);

            // Print count of characters
            // in between
            document.write(len - 2);

            // Print last character
            document.write(str[len - 1]);
        }

        // Driver Code
        let str = "internationalization";
        abbreviateWord(str);

    </script>

Output

i18n

Time Complexity: O(1)
Auxiliary Space: O(1)
