HERE ARE THE FIVE CHAINS
XXXXXX XXXXXX XXXXXX XXXXX XXXXX
I need to break 4 end links and use them to join the pieces back up
XX X XXXXXX X XXXXXX X XXXXX X XXXXX 15*4=60c
Of course if one small chain has less than 4 links then less joins will be needed.
If the shortest one is only 3 links then
XXX XXXXXX XXXXXX XXXXX XXXXX
becomes
XXXXXX X XXXXXX X XXXXX X XXXXX 15*3=45c
If the two shortest ones have 2 links each then
XX XX XXXXXX XXXXX XXXXX
becomes
X X XXXXXX X XXXXX X XXXXX 15*3=45c still 45cents
