This is the first thing I thought, and perhaps
the code I'd write...
# ASSERTION: array contains at least 2 elements
@v = (1,2,3,4,5);
$flag = 0;
$first = $v[0];
foreach ( @v[1,] ) { # Starts from second element
print "Examining $_...\n";
if ($_ != $first) {
$flag = 1;
last;
}
}
print "All elements are equal" unless $flag;
Or, using hashes...
(Smaller version, but it seems to me THIS is brute force)
@v = (1,2,3,4,5);
map { $set{$_} = 1 } @v;
# Elements are equal, unless set contains more than one element
@k = keys %set;
print "All elements are equal" unless $#k != 1;
See you
