Hint 2 of 2
Scan each junction between neighbours and mark the one place where it is left-hand to left-hand.
Show solution
Approach: count the matching hand-clasps
- Walk along the row and look at each pair of joined hands.
- Most joins are a right hand meeting a left hand; only one join is left hand to left hand.
- So the count is 1.
