一、  数论算法

1.求两数的最大公约数

function gcd(a,b:integer):integer;
begin
if b=0 then gcd:=a
else gcd:=gcd (b,a mod b);
end ;


2.求两数的最小公倍数

function lcm(a,b:integer):integer;
begin
if a<b then swap(a,b);
lcm:=a;
while lcm mod b>0 do inc(lcm,a);
end;


3.素数的求法
A.小范围内判断一个数是否为质数:

function prime (n: integer): Boolean;
var I: integer;
begin
for I:=2 to trunc(sqrt(n)) do
if n mod I=0 then begin
prime:=false; exit;
end;
prime:=true;
end;

在iis6启用压缩,网站,服务,前面两个打勾(http压缩)
最好,把临时目录设在别的地方,

文件名:MetaBase.xml

本来想把js 和css放到html那部分,测试的结果没有压缩成!
所以正确的结果应该放在下面的部分
Tags: , ,
utf-8下,php對長度的截取
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

<?php

mb_internal_encoding("UTF-8");  //這個一定要設,要不然就顯示"我們",你可以測試一下
$string = "我們還好了什麼和什麼";
$mystring = mb_substr($string,0,6);
echo $mystring;


?><br />
<?php
echo $string;
?>
