Have a perl brain-teaser: my @l = ('a', 'b', 'c'); for (@l) { my $n = 1; print shift @l while (@l and $n --> 0); print "\n"; } What's it print? Should be a, b, and c, right? But oh wait actually there's a bug somewhere, it only prints a and b. Probably just some stupid off-by-one, should be easy to solve, right? Ok so mak...

Okay, so I've got a piece of Python code which really needs optimizing. I need to iterate over every single pixel of a small (80x60) image and extract the RGB values from it. The code in the loop itself isn't too slow, but I'm doing it using nested for loops, which I assume add quite a bit of overhead... xr = xrange(80) yr = xrange(60)...

Is there any way to change the l...

Is there a way to print numbers from 1 to 100 without using any loops or conditions like "if"? We can easily do using recursion but that again has an if condition. Is there a way to do without using "if" as well? Also no repetitive print statements,or a single print statement containing all the numbers from 1 to 100. A solution in Java ...
Using jQuery I would like to loop through an array of links and load the contents of each link into a DIV after a set interval.
