WebMar 24, 2014 · 2. To efficiently be able to report the length of the linked list, you need to incriment it each time you add an element and decrement it each time you remove one. You're already doing the latter, but not the former. So, just add self.length += 1 somewhere in your enqueue method, then size () can simple be return self.length. WebJan 5, 2024 · Steps for implementing queue using linked list: 1. Enqueue Function Enqueue function adds an element to the end of the queue. It takes O (1) time.
