Rotating an array (Posted on 2004-04-19) Difficulty: 2 of 5
I have an array such as A-B-C-D-E-F-G-H-I-J-K I want to rotate it N places to the right; for example, if N=3, the array should end I-J-K-A-B-C-D-E-F-G-H

Assume that the only available operation is a FLIP method that can invert any portion of the array. For example, applied to the original array FLIP(3,6) would produce A-B-F-E-D-C-G-H-I-J-K.

Yes, that's exactly what he means to ask.

You have available the basic programmatic operators... for, while... do, do... while, repeat... until, if... then, integer variables with basic mathematical operators, and arrays (which includes an index method, of course, such as Characters[5] meaning the 'E' in the first array, assuming a 1-based array).

I'm sure you are welcome to use any language you'd like... C/C++, Pascal, Basic, Fortran, COBOL, etc....

And I'll bet an algorithm in pseudocode or even english will suffice (with proper precision).
