How can we check if a string 'Ra' appears at index 1 in a given string. If it appears return a string without 'Ra' otherwise return the original string.

Sample Input:
"Ram"
"Rat"
"Coding"

Expected Output:

m
t
Coding

Have not tested but it should work, please test this

public string GetTexts(string str)
  {
      var regex=new Regex(@"^\bRa(\w+)\b");
        if(regex.IsMatch(str))
        {
            Match m=regex.Match(str);
          return m.Groups[1].ToString();
        }
        else
        {
            return str;
        }
  }

Try

string text = "Coding";
if(text.Substring(0, 2) == "Ra")
	Console.WriteLine(text.Remove(0, 2));
else
	Console.WriteLine(text);
