用計數機將你既icq number + 4294967296 # b7 h6 f$ t. O; a# s9 P+ ?7 L
將計出黎個數 post 去 ICQ→加入→搜尋" k& h8 v7 ^ Q9 I
就發現搜尋結果係........

好簡單, ICQ 應該係 Visual C++ 寫的 , 而係 Visual C++ 入面
Maximum value for a variable of type "unsigned int" 係 4294967295 (0xffffffff) 3 R$ J( O9 o6 S/ [: A
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)7 P" e! i/ j8 Q
e.g.
0 + 4294967295 = 4294967295 (max) E. P* F- [. h( b) @
1 + 4294967295 = 0 + 4294967296 = 0 (because of overflow)$ S9 Q; V# E0 n' T! U% S; w. G' {
and so on....
