Write a program which returns list of all files having same content from the directory (including sub directory).
Example:
Input:
/a
/b
/c
x.txt
y.txt
/d
z.png
w.jpeg
/e
k.log
Output: [["a/b/c/x.txt", "a/e/k.log"], ["a/b/c/y.txt", "a/b/d/z.png"], ["a/b/d/w.jpeg"]].Note: file extension does not matter.
