- Control string can only switch from 1 to 0 not from 0 to 1
Setp 0 - Initiliaze Control String
Control: 11111111111111111
Step 1 - compare line 1 and 1+1
Line 1: /foo/bar/xzy
Line 2: /foo/bar/xzy/asdf
Control: 11111111111100000
Step 2 - compare line 2 and 2+1
Line 2: /foo/bar/xzy/asdf
Line 3: /foo/bar/xasdf
Control: 11111111110000000
Setp 3
Line 3: /foo/bar/xasdf
Line 4: /bar/foo/asdf
Control: 10001000100000000
Step4
Line 4: /bar/foo/asdf
Line 5: /bar/asdf/foo
Control: 10000000000000000
Step5: Count how many 1 are in the control string, beginning from left, breaking at first 0
Step6: remove that many characters from the beginning of each source string.
