１個好得意既野**

CHUNGYIP!

用計數機將你既icq number + 4294967296 % Y1 C2 _+ ]2 b
將計出黎個數 post 去 ICQ→加入→搜尋
2 \3 m/ t8 X' s就發現搜尋結果係........# p! d: P( p3 b9 P/ D* A- v8 R0 K
一個你都識既人!!!!

* [- d5 R# A5 t' X) b個 value 過左呢個 range 就會 overflow , 佢只會理最後個32bits 數 (即係好似返返轉頭 , 循環咁)( \& `" w) V- P1 L( a% b
e.g.

1 + 4294967295 = 0 + 4294967296 = 0 (because of overflow)
