Pictorial Presentation:
Sample Solution:
C# Sharp Code:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
public class Exercise42
{
public static void Main( )
{
// Prompt the user to input a string
Console.Write("Input a string: ");
// Read the input string and store it in the variable 'str'
string str = Console.ReadLine();
// Check if the length of the input string is less than 4 characters
if (str.Length < 4)
// If the length is less than 4, convert the whole string to uppercase and display it
Console.WriteLine(str.ToUpper());
else
// If the length is 4 or greater, convert the first 4 characters to lowercase
// and concatenate the rest of the string as is, then display the modified string
Console.WriteLine(str.Substring(0, 4).ToLower() + str.Substring(4, str.Length - 4));
