dir_euler
Write a function "dir_euler(digraph)" that takes in a connected, directed graph as its input, and then determines whether or not a directed Eulerian circuit exists.
After compiling the above cell, you should be able to compile the following cell and obtain the desired outputs.
print(dir_euler({"A" : ["A", "B", "C"], "B" : ["A"], "C" : ["A"]}),
dir_euler({"A" : ["B", "D"], "B" : ["A", "D"], "C" :
This should return
True False
["C", "D"], "D" : []}))
