Nature of problem:
The program segment determines the positions of different entries in two ordered lists of numbers. This is done for the analysis of complex spectra using the Unitary Group methods.

Solution method:
Iterative 'compare' statements.

Restrictions:
As given, the program treats only cases where, at most, two entries differ.

Running time:
Depending on the length of the list to be analyzed. Typically for 10 numbers, 10-15 ms.
