Algorithm 4K-RLE Pseudocode

$v1\leftarrow$ read input value   $count=1$   while there are still input values do     $v2\leftarrow$ read next input value     if ($|v1-v2|\le K$) then       $count=count+1$     else       output ($count,v1$)       $v1\leftarrow v2$       $count=1$     end if   end while   output ($count,v1$)
