@ -409,7 +409,7 @@ so the median is 2.
|

The median is an optimal choice,
|
||||
because if $x$ is smaller than the median,
|
||||
the sum becomes smaller by increasing $x$,
|
||||
and if $x$ is larger then the median,
|
||||
and if $x$ is larger than the median,
|
||||
the sum becomes smaller by decreasing $x$.
|
||||
Hence, the optimal solution is that $x$
|
||||
is the median.
