Digit Word.

A digit word is a word where, after possibly removing some letters, you are left with one of the single digits:
ONE, TWO, THREE, FOUR, FIVE, SIX, SEVEN, EIGHT or NINE.
For example:
• BOUNCE and ANNOUNCE are digit words, since they contain the digit ONE.
• ENCODE is not a digit word, even though it contains an O, N and E, since they are not in order.
 

Here's my code on Delphi


unit Unit1;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls;

type
  TForm1 = class(TForm)
    Edit1: TEdit;
    Button1: TButton;
    Memo1: TMemo;
    procedure proses;
    procedure FormCreate(Sender: TObject);
    procedure Button1Click(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;
  digit,cdigit:array[1..9] of string;

implementation

{$R *.dfm}

procedure TForm1.FormCreate(Sender: TObject);
begin
  memo1.Text:='';
  digit[1]:='one';
  digit[2]:='two';
  digit[3]:='three';
  digit[4]:='four';
  digit[5]:='five';
  digit[6]:='six';
  digit[7]:='seven';
  digit[8]:='eight';
  digit[9]:='nine';
end;

procedure tform1.proses;
var s:string;
    i,j,k,n:integer;
    c:array[1..9]of integer;
    ck:array[1..9]of boolean;
begin
  memo1.Text:='';
  s:=edit1.Text;
  memo1.Lines.Append(s);
  memo1.Lines.Append('');
  n:=length(s);
  for i:=1 to 9 do begin
    cdigit[i]:='';
    c[i]:=1;
    ck[i]:=true;
  end;

  //looking for char
  for i:=1 to 9 do begin
    for j:=1 to length(digit[i]) do begin
      if ck[i]=true then begin
       ck[i]:=false;
       for k:=c[i] to n  do begin
        if s[k]=digit[i][j] then begin
          ck[i]:=true;
          cdigit[i]:=cdigit[i]+s[k];
          c[i]:=c[i]+1;
          break;
        end;
       end;
      end;
    end;
  end;
  //compare
  for i:=1 to 9 do begin
    memo1.Lines.Append(cdigit[i]);
  end;

end;
procedure TForm1.Button1Click(Sender: TObject);
begin
  proses;
end;

end.
