用計數機將你既icq number + 4294967296 4 B4 U N7 m- a9 F: E
將計出黎個數 post 去 ICQ→加入→搜尋
就發現搜尋結果係........4 T6 T; k7 @# ]# Z/ K

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) 8 ~: X s% A2 M% z0 Y* H# ^
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)2 Q8 @8 S. s7 D* L0 ?- h7 g
and so on..../ y, C$ a5 l! q0 B
0 g$ f4 P7 E( F O
