 Colored Board Baffle (Posted on 2022-09-13)
Precisely 7 boards are arranged in a straight line. Their colors are:
blue, brown, green, orange, purple, red, and yellow - albeit not necessarily in that order.

It is known that:
1. Red is next to blue.
2. Purple is somewhere to the left of green.
3. There is precisely one board between yellow and red.
4. There are exactly two boards between brown and blue.
5. Blue is the 4th board from the left.
6. Orange is directly between yellow and purple.
Determine the precise order of these seven boards.

Their ordered placement is:
bl br gr or pu re ye
4  7  6  2   1  5   3

Which gives:

purple orange yellow blue red green brown

program is here

(One day I will write a general permutation subroutine.)
