１個好得意既野**

CHUNGYIP!

用計數機將你既icq number + 4294967296
( j+ U( w+ I) c: ]9 i將計出黎個數 post 去 ICQ→加入→搜尋& l  I, ?% D8 W5 F0 {  Q! c2 ]9 z
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 s+ u7 ^/ K) L$ q1 `
Maximum value for a variable of type "unsigned int" 係 4294967295 (0xffffffff) & }- [+ `4 B3 {* C" H! h$ s
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)
/ j0 z+ F$ ?. k3 @$ \+ De.g.
' }2 i" z& H: x; X4 c0 + 4294967295 = 4294967295 (max)
, q" D2 {2 M% o! w$ ?7 |7 w1 + 4294967295 = 0 + 4294967296 = 0 (because of overflow)
