perplexus.info :: Numbers : Any order will do

Any order will do (Posted on 2005-07-12)

The numbers from 1 to 2n are separated into two lists of n numbers each, A and B; elements are ordered so a₁<a₂<...<a_n and b₁>b₂>...>b_n.

How much is |a₁-b₁|+|a₂-b₂|+...+|a_n-b_n|?

Since it didn't show up correctly before, 'Ём' is supposed to be 'less than or equal to'
