用計數機將你既icq number + 4294967296 0 q+ ~2 [* [0 }3 Q- K& C
將計出黎個數 post 去 ICQ→加入→搜尋# d* X' h. e% Q1 F3 v% J
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, U8 t1 M" O* T' h& T
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)
e.g.
0 + 4294967295 = 4294967295 (max)
1 + 4294967295 = 0 + 4294967296 = 0 (because of overflow)
and so on....5 @5 u; u9 U7 c1 F- H s& l# y
