C#: Create a new string from a given string without the first two characters
Remove First Two Except 'p' and 'y'
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".
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.WriteLine(test("press")); // Pass "press" to the test function and display the result
Console.WriteLine(test("jython")); // Pass "jython" 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 >= 2) // If the length of 's1' is greater than or equal to 2
{
// If the character at index 1 of 's1' is not equal to "y", remove the character at index 1
if (String.Compare(s1.Substring(1, 1), "y") != 0)
{
s1 = s1.Remove(1, 1);
}
// If the character at index 0 of 's1' is not equal to "p", remove the character at index 0
if (String.Compare(s1.Substring(0, 1), "p") != 0)
{
s1 = s1.Remove(0, 1);
}
}
else if (s1.Length > 0 && String.Compare(s1.Substring(0, 1), "p") != 0)
{
// If 's1' has a length greater than 0 and the character at index 0 is not "p", remove the character at index 0
s1 = s1.Remove(0, 1);
}
return s1; // Return the modified or unchanged 's1'
}
}
}
Sample Output:
cab python pess ython
Flowchart:

Go to:
PREV : Remove First Two if Start and End Match.
NEXT : Remove 'a' if at Start or End.
