$2.$A $-$ Applying Algorithms

In this step, you will apply the three uninformed search algorithms to $100$ different instances of the Route Planning environment, recording various metrics for each algorithm$/$environment pair. Starter code has been provided for you in the cell below.

The outer loop in the cell below will execute $100$ times. Each time it runs, it creates a new Route Planning environment with $800$ sites. Each time the inner loop executes, a different search algorithm will be applied to the current environment. After applying the algorithm, the path length, path cost, and search time for that search should each be recorded in the appropriate dictionaries.

Complete the cell below by filling in the blanks to defined the variables p$,$ c$,$ and t as described in the comments below.
