In December, Amоs wаs tаlking with his 80-yeаr-оld grandfather abоut the COVID-19 vaccine. Amos asked his grandfather how likely he was to get vaccinated. His grandfather answered – “Probably about 90%.” In January, when Amos was speaking with his grandfather again, his grandfather said, “I saw on the internet that the vaccine has a microchip in it that changes your DNA! That worries me a lot. There’s only a 10% chance that I’ll get vaccinated now.” Amos had heard these conspiracy theories before and walked his grandfather through all the evidence showing that these claims aren’t just false but are totally ridiculous. At the end of the conversation, Amos again asked his grandfather how likely he was to get vaccinated. His grandfather answered – “Probably about 75%.” The fact that Amos’s grandfather was still less likely to get vaccinated than he was in December, even after hearing that the information about microchips in the vaccine was false, is most consistent with what decision-making error?

Cоmplete the fоllоwing implementаtion of Dijkstrа's shortest pаth algorithm. This is similar to P210.ShortestPath, but you can make use of the private helper methods isVisited to check if a node is visited and setVisited to mark a node as visited and extend to extend a path with an edge. The code for those helper methods is omitted below. Edge objects have a predecessor and successor field for references of the two nodes the edge connects. Note: no need to type any of the existing lines of code in your response to this question. private boolean isVisited(Node n) { /* omitted */ }private void setVisited(Node n) { /* omitted */}private Path extend(Path toExtend, Edge toAdd) { /* omitted */ }private PriorityQueue initQueue() { /* omitted */ }public Path computeShortestPath(Node start, Node end) { PriorityQueue pq = initQueue(); while (!pq.isEmpty()) { Path currentPath = pq.poll(); if (!isVisited(currentPath.endNode)) { setVisited(currentPath.endNode); if (currentPath.endNode != end) { for (Edge e: currentPath.endNode.edgesLeaving) { // TODO: write this for loop body code } } else { return currentPath; } } } throw new NoSuchElementException();}
