Given a string that represents a file structure where directory and file names are on separate lines and where these names are indented with a tab to show which directories they are stored under, return the length of the absolute path to a file that has the most characters.
For example, given "dir1\n\tsubdir\n\t\tfile1.txt\n\tfile2.txt"
, the
file structure is:
dir1
subdir
file1.txt
file2.txt
And the absolute path to a file with the most characters is
"dir1/subdir/file1.txt"
.
