Dijkstra algorithm

implemented with a two-dimensional array

int e[10][10];
int dis[10], book[10];
int inf = 99999999;
int n, m;

			else e[i][j] = inf;
	
	//read in edge

	for(int i = 1; i <= m; i++){
		cin >> t1 >> t2 >> t3;
		e[t1][t2] = t3;
	}	
	
	//initialize dis array
	for(int i = 1; i <= n; i++)
		dis[i] = e[1][i];
		
	//initialize book array
