huffman tree generator

John determine the minimum amount of money he can spend to createNPlanks. fj knows that he can cut the board in varous different orders which will result in different charges since the resulting intermediate planks are of different lengths. InputLine 1: One integer N, The number of planks Lines 2 .. N+ 1: each line contains a single integer describing the length of a needed plank OutputLine 1: One INTEGER: the minimum amount of money he must spend to make N-1 cuts Sample Input 3858 Sample outpu

Problem Description recently, Bob has just learnt a naive sorting algorithm:merge sort. Now, Bob receives a task from Alice. Alice would give Bob N sorted sequences, and the i-th sequence includes AI elements. Bob need to merge all of these sequences. He can write a program, which can merge no more than K sequences in one time. The cost of a merging operation is the sum of the length of these sequences. Unfortunately, Alice allows this program to use the no more than T cost. So Bob wants to know

#include "List" can be used for Huffman tree to build a list method of selecting the number of alternative heap

heap to get a new heap, which consumes 12 of the energy. So Xiao Ming spent a total of physical =3+12=15, can prove that 15 is the minimum physical consumption value. Input: Each set of data input consists of two rows, the first line is an integer n (1 Output: For each set of inputs, output an integer and wrap the value, which is the minimum physical cost. The input data guarantees that this value is less than 2^3

), where the first row of 2 positive integers represents the n heap of fruit and the maximum number of heaps of m that can be combined each time the merge, starting with n numbers from the second row, representing the weight of the N heap fruit (1~500), separated by a space between the number and the number.Output contains only a positive integer that represents the minimum total cost required to combine the n heap of fruit into 1 heaps.Sample Input 7 3 45 13 12 16 9 5 22 Sample Output This

Use Java to create Huffman tree code as follows: Note All in the code said, the specific principle is very simple, I will not say more: Package data_structure; Import java.util.ArrayList; Import java.util.Collection; Import java.util.Collections; Import java.util.LinkedList; Import java.util.List; public class Huffmantree {public static class node

In fact, this is Huffman tree, a start with priority queue write time-out, and later found that no priority queue, because each time the added value is always greater than before, then only need to use the normal queue can be, and this queue is monotonically increment, and then take the original array of the head or the head of the monotonous queue can be. But without taking into account (n-1)% (k-1) ==0, t
