Problem 1429. Remove entire row and column in the matrix containing the input values

Remove the entire row and column from the matrix containing specific values. The specified value can be a scalar or a vector. For example x is given by x =

     8     1     6
     3     5     7
     4     9     2

and I specify an input value of n=3. The value 3 is in 2nd row and 1st column. So the output matrix should remove entire 2nd row and 3rd column. Output:[ 1 6; 9 2]

remember the input value can be vector too !
