Function
int inDegree(const T& x);
Get the in degree of a specified vertex.
Parameters
x is label of specified vertex.
Return value
Return in degree of specified vertex.
Example
#include "HKUAL_graph.h"
#include <iostream>
using namespace std;
using namespace HKUAL;
int main(){
DirectedGraph<string> g;
g.addVertex("A");
g.addVertex("B");
g.addVertex("C");
g.addEdge("A", "B");
g.addEdge("A", "C");
cout << g.inDegree("A") << endl;
cout << g.inDegree("B") << endl;
return 0;
} |
Output
Time Complexity
, for is number of vertices.
