-- split a string into array
function split(s, delimiter)
    result = {};
    for match in (s..delimiter):gmatch("(.-)"..delimiter) do
        table.insert(result, match);
    end
    return result;
end
 
s = split(io.read(), [[ ]])
 
a = tonumber(s[1])
b = tonumber(s[2])
 
s = 0
for i = a, b do
    s = s + i * i
end
 
print(s)
-- split a string into array

	result = {};
	for match in (s..delimiter):gmatch("(.-)"..delimiter) do
		table.insert(result, match);
	end
	return result;
end

s = split(io.read(), [[ ]])

a = tonumber(s[1])
b = tonumber(s[2])

s = 0
for i = a, b do
	s = s + i * i
end

print(s)

The solution is to implement a loop to sum the squares of each number given a range.
