What is the shortest absolute path corresponding to the following relative path? ./hw/ ../../../etc/ That is, if you do: cd ./hw/../../../etc/, what will be the absolute path of the new directory? Explain how you got there! Hint: the shortest absolute path is one that doesn't have a . . or . directory entry in it. (2 points)
