Extracted text: Problem Statement: You are given an ArrayList of ArrayLists, each inner ArrayList contains integers. Convert everything into streams, the outer ArrayList and the inner ones. Filter over the inner streams, only return odd sized streams. Map each element of the inner streams to 10 times that element, returning a list. Return an array of lists.
