Assignment 2 Template

Posted by Hui Wu Thursday 18 March 2021, 11:41:28 PM.

Dear All,

In the assignment template, the variable new is defined in AVLTreeNode *newAVLTreeNode(int k, int v ). new is an operator for creating an object in several object-oriented programming languages, so some compilers do not allow using new as a variable name. I have changed it to newNode . Please download the template again.

Sorry for the mistake.

Clarifications about the longest sublist

Posted by Hui Wu Monday 08 March 2021, 08:44:50 PM, last modified Monday 08 March 2021, 08:54:16 PM.

Dear All,

In the lecture today, I explained an improved algorithm for finding the longest sublist. However, the improved algorithm may be incorrect if the list contains duplicates.

Consider the list u={2, 11, 11, 12, 13, 13, 13, 25}. The longest sublist is {13, 13, 13}.

In the assignment specification, I have added the following additional assumption:

Assume that all the integers in the list pointed by u are distinct.

Under this assumption, you can have faster algorithm which does not need to test all the integers between min and max, where min is 2 (Not the smallest absolution of all the integers) and max is the largest absolute value of all the integers.

Hui
