449. On a shelf, a ten-volume collection of Ilf and Petrov's works stands in a random order. A librarian can take any volume from the shelf and place it in the fifth position, counting from the left. Will the librarian be able to arrange all the volumes in ascending order of their numbers using several such operations?
$\triangle$ Let's take volume No. 1 and place it in the fifth position. In addition, all volumes that were to its left will also be placed in sequential order, one by one, in the fifth position. As a result, the first volume will end up in the first position from the left.

Now let's place volume No. 10 in the fifth position, followed by all volumes that were to its right. Then it will end up in the tenth position.

Similarly, without touching volumes No. 1 and No. 10, let's place volumes No. 2 and No. 9, No. 3 and No. 8, No. 4 and No. 7, and volume No. 6 in their respective positions. After this, volume No. 5 will end up in the fifth position.

Answer: will be able to.
