感觉学习语言的话,函数是个重头戏。来看一下Lua的函数是神马样纸的东东!
一.简单的函数例子
--一个简单的函数:阶乘
function factorial(num)
if num == 0 then
return 1
else
return num * factorial(num - 1)
end
end恩,这就是个函数。function关键字,说明这是个函数,然后是函...

示例代码(1)
decimal Factorial(int n)
{
if (n == 0)
return 1;
else
return n * Factorial(n - 1);
}
【分析】
阶乘(factorial),给定规模 n,算法基本步骤执行的数量为 n,所以算法复杂度为 O(n)。
示例代码(2)
int FindMaxElement(int[] array)
{
int max = array[0]...
