Using an array of K pointers

1. Given a singly-linked list of length k, reverse the order of the elements
2. Given a singly-linked list of length 2*k, reverse the order of the first k elements, without touching the last k elements. Return a pointer to the k^th element (counting from zero).
3. Given a singly-linked list of length 2*k, reverse the order of the last k elements.
4. Given a singly-linked list of length 3*k, reverse the order of the middle k elements. return a pointer to the 2*k^th element (counting from zero).
5. Put everything together to get the solution to your problem.

Can anyone point me in the right direction?

To ensure consistent results when creating a font, do not specify OEM_CHARSET or DEFAULT_CHARSET. If you specify a typeface name in the lpszFace parameter, make sure that the fdwCharSet value matches the character set of the typeface specified in lpszFace.

Quote:

The font mapper does not use the DEFAULT_CHARSET value. An application can use this value to allow the name and size of a font to fully describe the logical font. If a font with the specified name does not exist, a font from any character set can be substituted for the specified font. To avoid unexpected results, applications should use the DEFAULT_CHARSET value sparingly.
