How to prove that:
Let's say we have two binary heap trees H1 and H2 with size N. If their inorder traversals are the same, prove that H1=H2 by induction on N.

I'm just wonder, what the differences are between creating a BMP file algorithm and JPG file algorithm ?
If you know the others images' format algorithm, please post them.
Thanks.

Hii..
Can anybody help me to find an algorithm in Java code to find synonyms of a search word based on the context and I want to implement the algorithm with WordNet database.
For example, "I am running a Java program". From the context, I want to find the synonyms for the word "running", but the…

Hello,
Im doing a Java application and Im facing some doubts in which concerns performance.
I have a PriorityQueue which guarantees me the element removed is the one with greater priority. That PriorityQueue has instances of class Event (which implements Comparable interface). Each Event is associated…

So I have Image like this
I want to get something like this (I hevent drawn all lines I want but I hope you can get my idea)
I need algorithm for finding all straight lines on it by just reading colors of pixels. No hard math, no Haar, no Hough. Some algorithm which would be based on points…

So i implemented a Quad tree in Java for my 2D game and everything works fine except for when i run my collision detection algorithm, which checks if a object has hit another object and which side it hit.My problem is 80% of the time the collision algorithm works but sometimes the objects just go…

After removing the minimum element in a binary heap, i.e. after removing the root, why is the last leaf then assigned to the root and sifted down?
Why not take the lesser child of what used to be the root and just keep sifting up all the children? Isn't this the same amount of operations, so why…

Is it even possible to implement a binary heap using pointers rather than an array? I have searched around the internet (including SO) and no answer can be found.
The main problem here is that, how do you keep track of the last pointer? When you insert X into the heap, you place X at the last pointer…

Trying to think of a lower bound to the position of say, the nth largest key in a max-heap. Assuming the heap's laid out in array. The upper bound's min(2^n-2, array size -1) i think, but is it always lower bounded by 0?

As an exercise in Haskell, I'm trying to implement heapsort. The heap is usually implemented as an array in imperative languages, but this would be hugely inefficient in purely functional languages. So I've looked at binary heaps, but everything I found so far describes them from an imperative viewpoint…
