Book exchange in ssumethods.com
Imagine three people who are not known to each other called A, B and C are reading three books called “a”, ”b” and “c”. The person A would like to read “b” next. B prefers “c” and C prefers “a” as their next books. Because the three do not know each other, they are unaware that they can complete a circle of exchanges to accomplish that purpose.
Our effort is to show these possibilities to our users. Identifying head-to-head exchange (where A wants “b” and B wants “a”) is relatively easy if they are tabulated. However, former is quite a tedious job even though only three people are involved. Job becomes increasingly difficult when the number of people who can complete the circle increases.
