I answered him by saying Get a byte array and Get each character of String, Convert it to ASCII number and mark the position of byte array as that of ASCII number

var inputValue = "aabcdefgghi" ;
var result = OnlyOnceCheck(inputValue);
Console.WriteLine(result.ToString());
public static bool OnlyOnceCheck(string input)
{
return input.GroupBy(x => x).Any(g => g.Count() > 1);
}
