Book exchange

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.

CIRCLES OF EXCHANGE WITH 3. 5 AND 6 USERS

When a lot of combinations are available (A►B,B►C,C►D,D►E,E►F,F►A) it is possible to match them to achieve the desired outcome. If one or two combinations are missing (If we think it is B►C), that again can be shown in the result list.

The significance of core value of ssumethods.com emerges at this point. It will show you combinations up to seven people who are required to execute a perfect exchange.

It may also indicate which possible combinations are currently missing in order to complete a circle.
