下面是补充代码的实现:
#include <iostream>
using namespace std;
#define MAX_VERTEX_NUM 100
// 边结点
typedef struct ArcNode {
int adjvex; // 邻接点在顶点数组中的位置下标
struct ArcNode *nextarc; // 指向下一个邻接点的指针
int weight; // 权值
}ArcNode;
// 顶点结点
typedef struct VNode {
int data; // 顶点数据
ArcNode *firstarc; // 指向第一个邻接点的指针
}VNode, AdjList[MAX_VERTEX_NUM];
// 图
typedef struct {
AdjList vertices;
int vexnum, arcnum; // 顶点数和边数
}ALGraph;
void DFS(ALGraph G, int i, bool visited[]) {
visited[i] = true;
cout << G.vertices[i].data << " ";
ArcNode *p = G.vertices[i].firstarc;
while (p) {
if (!visited[p->adjvex]) {
DFS(G, p->adjvex, visited);
}
p = p->nextarc;
}
}
void DFSALGraph(ALGraph G,int i) {
bool visited[MAX_VERTEX_NUM];
for (int j = 0; j < G.vexnum; j++) {
visited[j] = false;
}
DFS(G, i, visited);
}
int GetGraphWeight(ALGraph G) {
int sum = 0;
for (int i = 0; i < G.vexnum; i++) {
ArcNode *p = G.vertices[i].firstarc;
while (p) {
sum += p->weight;
p = p->nextarc;
}
}
return sum;
}
int GetNode(ALGraph G) {
int count = 0;
for (int i = 0; i < G.vexnum; i++) {
int outDegree = 0, inDegree = 0;
ArcNode *p = G.vertices[i].firstarc;
while (p) {
outDegree++;
p = p->nextarc;
}
for (int j = 0; j < G.vexnum; j++) {
if (j != i) {
ArcNode *q = G.vertices[j].firstarc;
while (q) {
if (q->adjvex == i) {
inDegree++;
}
q = q->nextarc;
}
}
}
if (outDegree > inDegree) {
count++;
}
}
return count;
}
这样就完成了对深度遍历邻接表、计算图中所有边的权值之和和计算图中出度大于入度的结点个数的补充代码实现。请注意,以上代码只是一个示例,具体实现可能因为输入数据结构等因素而有所调整。
