Sorting a vector of custom objects
...
Sorting such a vector or any other applicable (mutable input iterator) range of custom objects of type X can be achieved using various methods, especially including the use of standard library algorithms like
sort,
stable_sort,
partial_sort or
partial_sort_copy.
Since most of the techniqu...
Why are function pointers and data pointers incompatible in C/C++?
...ationale says:
6.3.2.3 Pointers
C has now been implemented on a wide range of architectures. While some of these
architectures feature uniform pointers which are the size of some integer type, maximally
portable code cannot assume any necessary correspondence between different pointer type...

OverflowError: (34, 'Numerical result out of range')
The inf value is considered a very special value with unusual semantics, so it's better to know about an OverflowError straight away through an exception, rather than having an inf value silently injected into your ...
Rolling median algorithm in C
...queries but is more flexible. Best of all the "N" is the size of your data range. So if your rolling median has a window of a million items, but your data varies from 1..65536, then only 16 operations are required per movement of the rolling window of 1 million!!
The c++ code is similar to what Den...

...alling, axhline() and axvline() draw lines that span a portion of the axis range, regardless of coordinates. The parameters xmin or ymin use value 0.0 as the minimum of the axis and 1.0 as the maximum of the axis.
Instead, use plt.plot((x1, x2), (y1, y2), 'k-') to draw a line from the point (x1, y1...

The most efficient way to implement an integer based power function pow(int, int)
