From a CTF challenge, a easy pwn(elf). I could probably have done it in better way, but anyway I ended up with the flag in a array looking like this.

```
['4:a', '27:a', '33:a', '39:b', '5:c', '31:c', '44:c', '45:c', '18:d', '37:d', '2:e', '21:e', '25:e', '29:e', '36:e', '46:e', '35:g', '3:h','32:h', '17:i', '6:k', '10:l', '24:l', '9:n', '34:n', '22:o', '16:p', '20:p', '23:p', '28:r', '13:s', '42:s', '47:s', '48:s', '14:t', '15:u','43:u', '1:w', '11:y', '40:y', '8:O', '7:{', '49:}', '12:_', '19:_', '26:_', '30:_', '38:_', '41:_','0:$']

```

Is it possible to sort this array in easy way?
