219A - k-String

3064232

I used varianbles: s,t,answer: string;

So strings in FPC can have up to 255 chars, i think. But test case can contain: 1 ≤ |s| ≤ 1000 .

If test case is: "2 aaaa" Answer is: "aaaa"

If test case is: "2 a{x 254}" Answer is: "a{x 254}" — http://ideone.com/h7t6hg

If test case is: "2 a{x 256}" Answer by my program is: "-1" — http://ideone.com/S9ZefD But I think expected was "a{x 256}"

Hm :/ , what does it mean?
