Write an algorithm that does an in-order traversal of a tree recursively. Now, write the same algorithm iteratively.
Write a function to remove all redundant characters in a given string.
Remove duplicates from a linked list. O(n) time.
Not hard at all.
Find the maximum subset sum in an array of numbers. Discuss complexity.
Design and implement an algorithm to determine if a binary tree is symmetric.
Given a 2D array, find the sum of all the elements in the array. O(n^2) solution is too slow, find ways to optimize (ended up adding a second parameter 2D array).
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?
