How to remove spaces from a string using JavaScript?
...s is the regex for "whitespace", and g is the "global" flag, meaning match ALL \s (whitespaces).

Remove trailing zeros
...rse("2.0044").ToString("G29")
2.0m.ToString("G29")
This should work for all input.
Update Check out the Standard Numeric Formats I've had to explicitly set the precision specifier to 29 as the docs clearly state:
However, if the number is a Decimal and the precision specifier is omitted, fix...

How to find time complexity of an algorithm
...term is 2 million and the second term is only 2.
For this reason, we drop all but the largest terms for large N.
So, now we have gone from 2N + 2 to 2N.
Traditionally, we are only interested in performance up to constant factors.
This means that we don't really care if there is some constant mu...

Convert date to datetime in Python
...lue representable by datetime and then getting its time component. Incidentally, datetime.min = datetime(MINYEAR, 1, 1, tzinfo=None) and has a time of 00:00:00. However, I think it is cleaner to explicitly create a 00:00:00 time either through time.min or time(0, 0, 0, 0).

Is there a reason that we cannot iterate on “reverse Range” in ruby?
...its start and end, not by its contents. "Iterating" over a range doesn't really make sense in a general case. Consider, for example, how you would "iterate" over the range produced by two dates. Would you iterate by day? by month? by year? by week? It's not well-defined. IMO, the fact that it's allo...
How to make graphics with transparent background in R using ggplot2?

Fastest way is using using rect, as all the rectangle elements inherit from rect:
p <- p +
theme(
rect = element_rect(fill = "transparent") # all rectangles
)
p
More controlled way is to use options of theme:
p <- p +
theme(
