﻿ C# - Make n copies of the first 3 characters of a string

# C#: Create a new string which contain the n copies of the first 3 characters of a given string

## C# Sharp Basic Algorithm: Exercise-26 with Solution

Write a C# Sharp program to create a string that is n (non-negative integer) copies of the first 3 characters of a given string. If the given string is shorter than 3, return n copies of the string.

Sample Solution:-

C# Sharp Code:

``````using System;

// Namespace declaration
namespace exercises
{
// Class declaration
class Program
{
// Main method - entry point of the program
static void Main(string[] args)
{
// Displaying the output of the 'test' method with different string inputs and integers
Console.WriteLine(test("Python", 2));  // Output: PytPyt
Console.WriteLine(test("Python", 3));  // Output: PytPytPyt
Console.WriteLine(test("JS", 3));      // Output: JSJSJS
Console.ReadLine();                    // Keeping the console window open
}

// Method to generate a string that repeats the first few characters 'n' times
public static string test(string s, int n)
{
var result = string.Empty;   // Initialize an empty string to store the resulting string
var frontOfString = 3;      // Define the number of characters to repeat

// Check if the defined number of characters to repeat exceeds the length of the input string
if (frontOfString > s.Length)
frontOfString = s.Length;  // Adjust the number of characters to repeat to the length of the input string

var front = s.Substring(0, frontOfString);  // Extract the specified number of characters from the beginning of the input string

// Loop 'n' times to concatenate the extracted characters to the result string
for (var i = 0; i < n; i++)
{
result += front;  // Concatenate the extracted characters 'n' times to the result string
}
return result;  // Return the resulting concatenated string
}
}
}
```
```

Sample Output:

```PytPyt
PytPytPyt
JSJSJS```
