Random number generation in lua

Two functions are required:

(1) math.randomseed(N): Receive an integer N as a random sequence seed

(2) math.random([n, [m]]): This function has three uses, respectively, without parameters, at this time, a random floating point number between (0, 1) is generated; there is a parameter n, which generates 1 Integer between n and n; has 2 parameters n and m, and generates a random integer between n and m.

The most common method is

math.randomseed(os.time())

for i=0, 10 do
    local n = math.random(10)
    print(n)
N in end 

math.randseed(N) also changes, so that the random sequence generated each time can be guaranteed to be non-repeated (with a small probability).
