How to draw vertical lines on a given plot in matplotlib?
...he y-axis, while axvline takes ymin and ymax as a percentage of the y-axis range.
When passing multiple lines to vlines, pass a list to ymin and ymax.
If you're plotting a figure with something like fig, ax = plt.subplots(), then replace plt.vlines or plt.axvline with ax.vlines or ax.axvline, res...

...n); // 5 7 3 3 1

IntStream.range(0, size).map(i -> size - i - 1).map(list::get)
.forEach(System.out::println); // 5 7 3 3 1
// If list is RandomAccess (i.e. an ArrayList), less efficient due to sorting
IntStream.range(0, size).boxed().sorted(Co...
How can I pad an integer with zeros on the left?
...y. I had to zero pad and display a collection of unsigned ints that could range between 1 to 3 digits. It needed to work lightning fast. I used this simple method: for( int i : data ) strData += (i > 9 ? (i > 99 ? "" : "0") : "00") + Integer.toString( i ) + "|"; That worked very rapidly (so...

... 1 , 1 , 1 , 1 , $n ) );
This actually fails gracefully on values out of range for a day of the month (i.e. $n > 31) but we can add some simple inline logic to cap $n at 29:
date( 'S', mktime( 1, 1, 1, 1, ( (($n>=10)+($n>=20))*10 + $n%10) ));
The only positive value(May 2017) this fail...

What does the “Just” syntax mean in Haskell?

Functor provides a method called fmap, which maps functions that range over values from the base type (such as Integer) to functions that range over values from the lifted type (such as Maybe Integer). A function transformed with fmap to work on a Maybe value works like this:
