用計數機將你既icq number + 4294967296
將計出黎個數 post 去 ICQ→加入→搜尋
就發現搜尋結果係........' b0 b! v: o2 I q

好簡單, ICQ 應該係 Visual C++ 寫的 , 而係 Visual C++ 入面1 O/ V; C: ]% E' h
Maximum value for a variable of type "unsigned int" 係 4294967295 (0xffffffff)
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)' H3 Z; p. ^# |- H' [* ?1 b: b2 z
e.g.
0 + 4294967295 = 4294967295 (max)& I8 F% Y( }1 k& u$ d- }
1 + 4294967295 = 0 + 4294967296 = 0 (because of overflow)
and so on....
