Help with Getting Values from Table

You can loop through the table and check if that value is greater than either of the past values.

local numberTable = {10, 8, 5, 0, 1, 18, 27}

local highestnumber = 0

for i, v in pairs(numberTable) do
      local number = tonumber(v)
     if number > highestnumber then
        highestnumber = number
    end
end
print(highestnumber)

@XdJackyboiiXd21 beat me w/ the code.

I’ll just add that this assumes the list is not sorted. If you know it is sorted, then you can do a binary search instead to find values. And to get lowest/highest values, just grab the first/last value. That being said, it is not worth sorting a list just to do a binary search or find min/max.

Couldn’t agree more. Sorting the table is NOT the way to implement a min/max function since you would end up using an nlog(n) algorithm for something that can be solved in linear time.
