１個好得意既野**

CHUNGYIP!

用計數機將你既icq number + 4294967296 $ M$ ]; I' ~/ @3 a& G8 t
將計出黎個數 post 去 ICQ→加入→搜尋
. g7 n* K6 D5 ~, v  H7 K% E8 A5 D就發現搜尋結果係........& d$ o- s% f9 q8 }$ p/ B
一個你都識既人!!!!

Maximum value for a variable of type "unsigned int" 係 4294967295 (0xffffffff) , S0 |/ v7 `) @0 b6 W
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)0 r1 j0 o3 z! d1 h2 Q# _9 C
e.g.
6 s$ z% K$ c( Q8 R. F3 ~! c0 + 4294967295 = 4294967295 (max)
