--1st problem
table_element(table, number)
	return table[number]
end

--2nd problem
last_table_element(table)
	return table[#table]
end

--3th problem
last_second_table_element(table)
	return table[#table - 1]
end

--4th problem
lenght_of_array(table)
	return #table
end

--5th problem - I think on this about 30 mins!
reverse_table(table)
	local l = {}
	for n = 1, #table do
		l[#table + 1 - n] = t[n]
	end
return l
end


--6th problem - hardest one!
function table_in_palidrome(table)
        local n = math.floor(#table / 2)
        for p = 1, n do
                if table[p] ~= table[#table - p + 1] then
                        return false
                end
        end
        return true
end
