Write a program that simulates a "cd" Unix command in an abstract file system. The command takes two path strings from the command line and prints a new path or an error. The first path is a current directory. The second path is a new directory. Examples:

% mycd /abc/def ghi /abc/def/ghi % mycd /abc/def .. /abc % mycd /abc/def /abc /abc % mycd /abc/def /abc/klm /abc/klm % mycd /abc/def ../.. / % mycd /abc/def ../../.. / % mycd /abc/def . /abc/def % mycd /abc/def ..klm ..klm: No such file or directory
