convert binary tree to double linked list
Q2) Certain Customers buy kindle on day one and certain customers buy kindle on day two. Design an algorithm(optimum) to find customers who bought on both days. Each customer has a unique ID (Integer). (I forgot to consider case of duplicates,until she reminded), You need to write complete code(NOT just pseudo code within given time and read it out)
Find the maximum subset sum in an array of numbers. Discuss complexity.
Find the most frequent 3-page sequence in a web log.
2) This is the most important task in the group assesment where I think I would have failed. You will be given a code base with 30 Java files. There will be three milestones. Milestone 1) You need to find a way to map the products to shipping centers. The question was vague and I cant remember it exactly. This mapping can be done by identifying the cost of shipping for each area. Cost can in turn be calculated based on four different factors like air shipping, ground shipping and few others. Based on the customer requirement you need to make the products to shipping areas and return a list of product ids and their shipping cost list.
Heap Sorting. What data structure do you use to implement it? Time to access and sort. Code it.
Is it possible to sort using linear time a file with lots of numbers that contain duplicates, when there are no limits of resources or space?
62-63=1; Changing only one element (either digit or operand), make this statement true.
given an unsigned char array, find if there is a subarray whose elements sum up to a given value
