OUTPUT:
---------
The un-canonicalized path 2 is : A:/name_1/./name_2/../name_3
The return value is            : 1
The canonicalized path 1 is    : A:/name_1/name_3

The un-canonicalized path 3 is : A:/name_1/../name_2/./name_3
The return value is            : 1
The canonicalized path 1 is    : A:/name_2/name_3

The un-canonicalized path 4 is : A:/name_1/name_2/./name_3/../name_4
The return value is            : 1
The canonicalized path 1 is    : A:/name_1/name_2/name_4

The un-canonicalized path 5 is : A:/name_1/./name_2/./name_3/../name_4/..
The return value is            : 1
The canonicalized path 1 is    : A:/name_1/name_2

The un-canonicalized path 6 is : C:/..
The return value is            : 1
The canonicalized path 1 is    : C:/
