用計數機將你既icq number + 4294967296
將計出黎個數 post 去 ICQ→加入→搜尋* X" n9 F$ F$ [) _
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8 u8 k, }' s: [
Maximum value for a variable of type "unsigned int" 係 4294967295 (0xffffffff) 7 \0 N f; R: \# y0 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 l, L3 q. w+ H9 z8 N, L( D+ A
e.g.
0 + 4294967295 = 4294967295 (max)# T7 j- ~/ { `6 F# E
1 + 4294967295 = 0 + 4294967296 = 0 (because of overflow)
and so on....
