C#: Create a new list from a given list of strings where each element has "#" added at the beginning and end position
C# Sharp Basic Algorithm: Exercise-143 with Solution
Write a C# Sharp program to create a list from a given list of strings. Each element has "#" added at the beginning and end position.
Visual Presentation:
Sample Solution:
C# Sharp Code:
using System; // Importing the System namespace for basic functionality
using System.Collections.Generic; // Importing the namespace for working with collections
using System.Linq; // Importing the namespace for LINQ operations
namespace exercises // Defining a namespace called 'exercises'
{
class Program // Defining a class named 'Program'
{
static void Main(string[] args) // The entry point of the program
{
// Creating a List of strings and assigning the result of the 'test' method
List<string> mylist = test(new List<string>(new string[] { "1", "2", "3", "4" }));
// Displaying the elements of 'mylist' in the console
foreach (var i in mylist)
{
Console.Write(i.ToString() + " "); // Output each element followed by a space
}
}
// Method that takes a List of strings and adds '#' at the beginning and end of each string
public static List<string> test(List<string> nums_str)
{
// Using LINQ to append '#' at the start and end of each string in 'nums_str'
IEnumerable<string> s = nums_str.Select(x => "#" + x + "#");
// Converting the IEnumerable 's' to a new List and returning it
return s.ToList();
}
}
}
Sample Output:
#1# #2# #3# #4#
