１個好得意既野**

CHUNGYIP!

用計數機將你既icq number + 4294967296 2 Y2 X+ {# u; D
將計出黎個數 post 去 ICQ→加入→搜尋- h6 z- q; a  F. p
就發現搜尋結果係........
1 K& ^$ k% l2 b) }一個你都識既人!!!!

好簡單, ICQ 應該係 Visual C++ 寫的 , 而係 Visual C++ 入面8 ~' p+ o7 E  E, }
Maximum value for a variable of type "unsigned int" 係 4294967295 (0xffffffff)
* n: W# {' t1 j% \! b% B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)2 h6 P, a5 P3 k' m. m8 \
e.g.* ?' E: Q/ U5 _
0 + 4294967295 = 4294967295 (max)
4 y4 B2 ^2 ~6 D- f- c1 + 4294967295 = 0 + 4294967296 = 0 (because of overflow)8 S1 M8 c) M3 V9 {/ ~8 e
and so on....
