Dear Try this code: namespace problem { class Program { static void Main(string[] args) { string str = AbcdeaDFGfAf; char ch; int kj=0; int count=0count1=0; Console.Clear(); for(ch='A';ch { count=count1=0; for(j=0;j { if(str[j]==ch) count++; if(str[j]==(ch+32)) count1++; } if(( count>=2|| count1>=2)|| (count+count1)>=2) { for(k=1;k Console.Write(ch); for (k = 1; k Console.Write(char.ToLower(ch)); Console.WriteLine(); } } } } } Thanks Happy Coding

static void Test1() { // Ascii Code For 'A' = 65 // Ascii Code For 'B' = 66 // and so on... // Ascii Code For 'Z' = 90 // Ascii Code For 'a' = 97 // Ascii Code For 'b' = 98 // and so on... // Ascii Code For 'z' = 122 Hashtable characterTable = new Hashtable (); // initialize characterTable with keys 'A' to 'Z' having empty values. for ( int index=65; index { characterTable.Add(index  ); } //string input = AbcdeaDFGfAf; Console .WriteLine( Input:
 ); string input = Console .ReadLine(); int asciiCode = 0; int lowerCaseAsciiCode = 0; for ( int i = 0; i { // check if it's a character because we're only interested in characters. A-Za-z. if ( char .IsLetter(input[i])) { // ascii codes for characters are either 65-90 (A-Z) or 97-122 (a-z) asciiCode = input[i]; // check if it's uppercase if (asciiCode { characterTable[asciiCode] = input[i] + characterTable[asciiCode].ToString(); } else { // it's lower case lowerCaseAsciiCode = asciiCode - 32; characterTable[lowerCaseAsciiCode] = characterTable[lowerCaseAsciiCode].ToString() + input[i]; } } } Console .WriteLine(); // display output for ( int j = 65; j { string letters = characterTable[j] as string ; if (letters.Length > 1) { Console .WriteLine(letters); } } Console .Read(); }
