Can you provide a code to path with smallest product of edges with weight >= 1 and the other steps required given the following:
Path with smallest product of edges with weight >= 1 | Function to return the smallest product of edges.
If the source is equal to the destination.
Initialise the priority queue.
Visited array.
While the priority - queue is not empty.
Current node.
Current product of distance.
Popping the top - most element.
If already visited continue.
Marking the node as visited.
If it is a destination node.
Traversing the current node.
If no path exists.
Driver code.
Graph as adjacency matrix.
Input edges.
print ( gr ).
Source and destination.
Dijkstra"

#Here is code to path with smallest product of edges with weight >= 1 and the other steps required.
 def dijkstra ( s , d , gr ) :
	if ( s == d ) :
		return 0 ;
	pq = [ ] ;
	pq . append ( ( 1 , s ) ) ;
	v = [ 0 ] * ( len ( gr ) + 1 ) ;
	while ( len ( pq ) != 0 ) :
		curr = pq [ 0 ] [ 1 ] ;
		dist = pq [ 0 ] [ 0 ] ;
		pq . pop ( ) ;
		if ( v [ curr ] ) :
			continue ;
		v [ curr ] = 1 ;
		if ( curr == d ) :
			return dist ;
		for it in gr [ curr ] :
			if it not in pq :
				pq . insert ( 0 , ( dist * it [ 1 ] , it [ 0 ] ) ) ;
	return - 1 ;
if __name__ == " _ _ main _ _ " :
	n = 3 ;
	gr = { } ;
	gr [ 1 ] = [ ( 3 , 9 ) ] ;
	gr [ 2 ] = [ ( 3 , 1 ) ] ;
	gr [ 1 ] . append ( ( 2 , 5 ) ) ;
	gr [ 3 ] = [ ] ;
	s = 1 ; d = 3 ;
	print ( dijkstra ( s , d , gr ) ) ;
