１個好得意既野**

CHUNGYIP!

用計數機將你既icq number + 4294967296
* f! y( @% G# _% A' z% a- v5 j8 y將計出黎個數 post 去 ICQ→加入→搜尋2 [# R, N! _. I" o: ]' L
就發現搜尋結果係........, p) D7 z& ]% e' y% k* s8 w
一個你都識既人!!!!

Maximum value for a variable of type "unsigned int" 係 4294967295 (0xffffffff)
9 ~; M3 q, d" k+ i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)9 @/ V# Z0 s2 E4 \/ p
e.g.
