Again using reduce is the functional way to do it. The above 
basically boils down to:

int[] arr1 = [1, 2, 30];
int maxElement = arr1[1];
foreach( element; arr1[2..$] ) //2..$ is short hand for second 
till last ($) element
{
  maxElement = max( maxElement, element );
}
writeln( maxElement );

Sorry been using too much R, so my indexes are off by 1:

int[] arr1 = [1, 2, 30];
int maxElement = arr1[0];
foreach( element; arr1[1..$] ) //1..$ is short hand for second 
till last ($) element
{
  maxElement = max( maxElement, element );
}
writeln( maxElement );
