07-图6 旅游规划

有了一张自驾旅游路线图,你会知道城市间的高速公路长度、以及该公路要收取的过路费。现在需要你写一个程序,帮助前来咨询的游客找一条出发地和目的地之间的最短路径。如果有若干条路径都是最短的,那么需要输出最便宜的一条路径。输入格式:输入说明:输入数据的第1行给出4个正整数N、M、S、D,其中N(2≤N≤500)是城市的个数,顺便假设城市的编号为0~(N−1);M……

06-图2 Saving James Bond – Easy Version

This time let us consider the situation in the movie “Live and Let Die” in which James Bond, the world’s most famous spy, was captured by a group of drug dealers.……

05-树8 File Transfer

We have a network of computers and a list of bi-directional connections. Each of these connections allows a file transfer from one computer to another. Is it possible to send a fil……

05-树7 堆中的路径

将一系列给定数字插入一个初始为空的小顶堆H[]。随后对任意给定的下标i,打印从H[i]到根结点的路径。输入格式:每组测试第1行包含2个正整数N和M(≤1000),分别是插入元素的个数、以及需要打印的路径条数。下一行给出区间[-10000, 10000]内的N个要被插入一个初始为空的小顶堆的整数。最后一行给出M个下标。输出格式:对输入中给出的每个下标i……

04-树6 Complete Binary Search Tree

A Binary Search Tree (BST) is recursively defined as a binary tree which has the following properties:The left subtree of a node contains only nodes with keys less than the node&#……

05-树9 Huffman Codes

In 1953, David A. Huffman published his paper “A Method for the Construction of Minimum-Redundancy Codes”, and hence printed his name in the history of computer science……

06-图1 列出连通集

题目很简单,我没用教材上给的图结构,不然太麻烦了,这是个无加全的无向图。。。一个二维数组就搞定了 #include<iostream>#include<malloc.h>#include<queue>#define max 50using n……

03-树3 Tree Traversals Again

An inorder binary tree traversal can be implemented in a non-recursive way with a stack. For example, suppose that when a 6-node binary tree (with the keys numbered from 1 to 6) is……

04-树5 Root of AVL Tree

An AVL tree is a self-balancing binary search tree. In an AVL tree, the heights of the two child subtrees of any node differ by at most one; if at any time they differ by more than……

04-树7 二叉搜索树的操作集

本题要求实现给定二叉搜索树的5种常用操作。函数接口定义:BinTree Insert( BinTree BST, ElementType X );BinTree Delete( BinTree BST, ElementType X );Position Find( BinTree BST, ElementType X );Position Find……

04-树4 是否同一棵二叉搜索树

给定一个插入序列就可以唯一确定一棵二叉搜索树。然而,一棵给定的二叉搜索树却可以由多种不同的插入序列得到。例如分别按照序列{2, 1, 3}和{2, 3, 1}插入初始为空的二叉搜索树,都得到一样的结果。于是对于输入的各种插入序列,你需要判断它们是否能生成一样的二叉搜索树。输入格式:输入包含若干组测试数据。每组数据的第1行给出两个正整数N (≤10)和L,……

03-树2 List Leaves

Given a tree, you are supposed to list all the leaves in the order of top down, and left to right.Input Specification:Each input file contains one test case. For each case, the f……

03-树1 树的同构

给定两棵树T1和T2。如果T1可以通过若干次左右孩子互换就变成T2,则我们称两棵树是“同构”的。例如图1给出的两棵树就是同构的,因为我们把其中一棵树的结点A、B、G的左右孩子互换后,就得到另外一棵树。而图2就不是同构的。现给定两棵树,请你判断它们是否是同构的。输入格式:输入给出2棵二叉树树的信息。对于每棵树,首先在一行中给出一个非负整数N (≤10……

02-线性结构3 Reversing Linked List

Given a constant K and a singly linked list L, you are supposed to reverse the links of every K elements on L. For example, given L being 1→2→3→4→5→6, if K=3, then you must output ……

02-线性结构4 Pop Sequence

Given a stack which can keep M numbers at most. Push N numbers in the order of 1, 2, 3, …, N and pop randomly. You are supposed to tell if a given sequence of numbers is a po……

02-线性结构1 两个有序链表序列的合并

本题要求实现一个函数,将两个链表表示的递增整数序列合并为一个非递减的整数序列。函数接口定义:List Merge( List L1, List L2 );其中List结构定义如下:typedef struct Node *PtrToNode;struct Node { ElementType Data; /* 存储结点数据 */ P……

02-线性结构2 一元多项式的乘法与加法运算

设计函数分别求两个一元多项式的乘积与和。输入格式:输入分2行,每行分别先给出多项式非零项的个数,再以指数递降方式输入一个多项式非零项系数和指数(绝对值均为不超过1000的整数)。数字间以空格分隔。输出格式:输出分2行,分别以指数递降方式输出乘积多项式以及和多项式非零项的系数和指数。数字间以空格分隔,但结尾不能有多余空格。零多项式应输出0 0。输入样……
