How can I find the words consist of the letters inside the keyword in Lua?

Question

For example, I have a keyword \"abandoned\" and I want to find the words that contains letters of this keyword such as \"done\", \"abandon\", band\", from the arrays I stored t

Answer 1

Try this:

W={"done", "abandon", "band"}
for k,w in pairs(W) do
    W[w]=true
end

function findwords(s)
    for i=1,#s do
        for j=i+1,#s do
            local w=s:sub(i,j)
            if W[w] then print(w) end
        end
    end
end

findwords("abandoned")

If you don't have an array of words, you can load a dictionary:

for w in io.lines("/usr/share/dict/words") do
    W[w]=true
end
