n = 0 function () local n = n + 1 while n < 100 do math.random(100) end end
随机乘以1到100以内的数↑
全排列，可以产生N！种排列：
local N = 100
local array = {}
for i = 1 , N do
array[i] = i
end
for i = 1 , N do
local j = math.random(N - i + 1) + i - 1;
array[i],array[j] = array[j],array[i]
end
for i = 1 , N do
print(array[i])
end
从1加到100：
i = 1; sum = 0; while (i<=100) do sum = sum + i i = i + 1 end print (sum)
简算式：
sum = 100 * (100-1)/2
