C#: Create a new string from a specified string
C# Sharp Basic Algorithm: Exercise-84 with Solution
Write a C# Sharp program to create a new string from a string. In the case that the two characters at the beginning and end of the given string are the same, return the given string without the first two characters, otherwise return the original string.
Visual Presentation:
Sample Solution:-
C# Sharp Code:
using System; // Importing the System namespace
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
{
// Output the results of the test function with different strings as arguments
Console.WriteLine(test("abcab")); // Pass "abcab" to the test function and display the result
Console.WriteLine(test("Python")); // Pass "Python" to the test function and display the result
Console.ReadLine(); // Wait for user input before closing the console window
}
// Function definition of the test function that takes a string 's1' as input and returns a string
public static string test(string s1)
{
if (s1.Length > 1 && s1.Substring(0, 2) == s1.Substring(s1.Length - 2))
{
// If the length of 's1' is greater than 1 and the first two characters are the same as the last two characters
return s1.Substring(2); // Return 's1' starting from the third character
}
else
{
return s1; // Otherwise, return the input 's1' unchanged
}
}
}
}
Sample Output:
cab Python

Previous: Write a C# Sharp program to create a new string using 3 copies of the first 2 characters of a given string. If the length of the given string is less than 2 use the whole string.
Next: Write a C# Sharp program to create a new string from a given string without the first two characters. Keep the first character if it is "p" and keep the second character if it is "y".
