Time Complexity: Although it takes O(n) time to iterate through each element in the Queue, it is often efficient when dealing with small to moderate-sized Queues. For bigger Queues or more frequent queries, try improving the search process or using alternate data structures designed for quicker...

However, to demonstrate a similar functionality for lists, one could use a workaround or choose an appropriate method based on the time complexity of the data structure. For instance, converting a list to a string and then using find() to check for a substring can be an indirect approach,...
