﻿ C# - Return the string without the first or first two is a

# C#: Create a new string from a given string. If the first or first two characters is 'a', return the string without those 'a' otherwise return the original given string

## C# Sharp Basic Algorithm: Exercise-87 with Solution

Write a C# Sharp program to create a new string from a given string. Return the string without the first or first two 'a' 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.WriteLine(test("aacda")); // Pass "aacda" 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 the length of 's1' is 1 and the only character is "a", remove that character
if (s1.Length == 1 && s1.Substring(0, 1) == "a")
{
s1 = s1.Remove(0, 1);
}

// If the length of 's1' is greater than 1, perform the following checks:
if (s1.Length > 1)
{
// If the second character is "a", remove it
if (s1.Substring(1, 1) == "a")
{
s1 = s1.Remove(1, 1);
}

// If the first character is "a", remove it
if (s1.Substring(0, 1) == "a")
{
s1 = s1.Remove(0, 1);
}
}

return s1; // Return the modified or unchanged 's1'
}
}
}
```
```

Sample Output:

```bcab
python
cda
jython
```
