Write a program that uses a graph-based path planning algorithm to guide the driverless car for traveling between two city halls. 1- Write the function PathFinder where the input arguments to the function are the name of two cities and the search algorithm. a. Example: when you call the function PathFinder (VA, LA, A_Star), it returns the optimal path between Vancouver and Langley using A* algorithm. b. (required) the function should implement the A* algorithm Write a program that uses a graph-based path planning algorithm to guide the driverless car for traveling between two city halls. 1- Write the function PathFinder where the input arguments to the function are the name of two cities and the search algorithm. a.
