Problem 2172. Delete the rows in the middle

We will delete the rows in the middle and keep the first and the last rows.

For example if input is

 [1 2
  1 7
  1 8
  1 6
  1 5]

then output will be

 [1 2
  1 5]

keeping the first and the last rows. However there will be more than one row index and that makes this question challenging.

Note: Elements of input row index is always greater than or equal to 2.
