Reoder an array in mimum number of steps
You have the array 876501234. The numbers on the right of the 0 are given in ascending order (1234), the numbers on the left of the zero are given in descending order (8765). 0 is an empty position. A number can move either in an adjacent empty position, or it can jump one single number and land in an empty position. Number cannot "move back" (e.g. the ascending number can just move from right to the left, the descending viceversa). You want to get the array 123408765, with the minimum number of moves.
