The reference count of a string is checked before mutating a string. This allows reference count 1 strings to be mutated directly whilst higher reference count strings are copied before mutation. This allows the general behaviour of old style pascal strings to be preserved whilst eliminating the cost of copying the string on every assignment.
In computer science, the count-distinct problem [1] (also known in applied mathematics as the cardinality estimation problem) is the problem of finding the number of distinct elements in a data stream with repeated elements. This is a well-known problem with numerous applications.
The statistical treatment of count data is distinct from that of binary data, in which the observations can take only two values, usually represented by 0 and 1, and from ordinal data, which may also consist of integers but where the individual values fall on an arbitrary scale and only the relative ranking is important.

Quick count is a method for verification of election results by projecting them from a sample of the polling stations.. The similar Parallel Vote Tabulation (PVT) is an election observation method that is typically based on a representative random sample of polling stations and is employed for independent verification (or challenge) of election results.
The average silhouette of the data is another useful criterion for assessing the natural number of clusters. The silhouette of a data instance is a measure of how closely it is matched to data within its cluster and how loosely it is matched to data of the neighboring cluster, i.e., the cluster whose average distance from the datum is lowest.

Python-5, the latest member in the Python family of AAMs A Python-5 AAM being fired from Indian Air Force HAL Tejas fighter. The Python-5 [13] [14] is currently the most capable visual range air-to-air missile in Israel's inventory. As a short range air-to-air missiles, it is capable of "lock-on after launch" (LOAL), and has full-sphere/all ...
[1] If the real part of an entire function is known in a neighborhood of a point then both the real and imaginary parts are known for the whole complex plane, up to an imaginary constant. For instance, if the real part is known in a neighborhood of zero, then we can find the coefficients for n > 0 {\displaystyle n>0} from the following ...
Monty Python Live (Mostly) (also billed as Monty Python Live (Mostly): One Down, Five to Go [1]) was a variety show by the Monty Python comedy group at The O2 in London in July 2014. Planned as a single performance for 1 July, it was expanded to 10 shows due to the high demand for tickets.
