Suppose we have the list: mylist = [ [ "Hello", [ "Hi" ] ] ]  How do I check that list containing "Hello" and "Hi" exists in mylist, in specifically this structure without flattening it? All the solutions are flattening the list, but I need to check for specific structure, like this Array |_ —-|_ “Hello” ———|_ “Hi” ——. . . 
You can just ask whether it's in there: ["Hello", ["Hi"]] in mylist  Attempt This Online!
