１個好得意既野**

CHUNGYIP!

用計數機將你既icq number + 4294967296
& _+ W+ y0 F  [將計出黎個數 post 去 ICQ→加入→搜尋0 E7 O+ L/ l3 J5 v, v
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
, O) v- }; X* X1 F# ^Maximum value for a variable of type "unsigned int" 係 4294967295 (0xffffffff) 0 [' a( j! D! ~9 |+ q& O: q
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 N  R! y  _; `8 e3 W" q
e.g.
* U" M/ }# p: G( g( H4 E0 + 4294967295 = 4294967295 (max)
! N/ e7 O/ J2 |2 C: |: S/ Y1 + 4294967295 = 0 + 4294967296 = 0 (because of overflow)
! a1 [$ }0 C! J- k8 nand so on....
