１個好得意既野**

CHUNGYIP!

用計數機將你既icq number + 4294967296 3 x' z  Z/ h4 |: @7 ?. ^, x6 b
將計出黎個數 post 去 ICQ→加入→搜尋2 I  i' v* B+ M2 D; i9 z/ t
就發現搜尋結果係........
9 |7 r, G% _: w5 f4 b: i一個你都識既人!!!!

好簡單, ICQ 應該係 Visual C++ 寫的 , 而係 Visual C++ 入面4 L4 z  Q6 h( `6 h0 m: ?
Maximum value for a variable of type "unsigned int" 係 4294967295 (0xffffffff) # R( g- Z, o% e+ 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)- p( T$ d) F  T/ ^4 N% u$ P2 m
e.g.  C& e# g2 \% F/ Y1 A( P, _% `
0 + 4294967295 = 4294967295 (max)1 W( h3 I7 S- U
1 + 4294967295 = 0 + 4294967296 = 0 (because of overflow)" I" y; m9 e3 b/ d5 @; y
and so on....
