Initially: $$$a = [8,6,6,1,6,3,1,8,8,10]$$$.

Move $$$8$$$ from the front to the back, $$$a = [6,6,1,6,3,1,8,8,10,8]$$$.

Move $$$10$$$ to the back, $$$a = [6,6,1,6,3,1,8,8,8,10]$$$.

Move $$$1$$$ to the back, $$$a = [6,6,6,3,1,8,8,8,10,1]$$$.

Move the other $$$1$$$ to the back, $$$a = [6,6,6,3,8,8,8,10,1,1]$$$.
