NettetVisit vertex 0, setting its distance to 4 and its predecessor to vertex 1. Now start visiting from vertices at distance 4 from the source. That's just vertex 0, and its neighbor, vertex 1, has already been visited. We're done! Notice that because there is no path from vertex 3 to vertex 7, the search never visits vertex 7.

If k is 0 then we return the value of node and return. In the print function, we have root of tree, target and distance k as arguments. If the root is null we return -1. If the root is equivalent to the target we call percolate function with root and k as arguments. cyberpower cp850 software https://highland-holiday-cottage.com
