  2. Document layout analysis - Wikipedia

    For each symbol, determine its k nearest neighbors where k is an integer greater than or equal to four. O`Gorman suggests k=5 in his paper as a good compromise between robustness and speed. The reason to use at least k=4 is that for a symbol in a document, the two or three nearest symbols are the ones right next to it on the same text line.

  3. Three-way comparison - Wikipedia

    In C++, the C++20 revision adds the spaceship operator <=>, which returns a value that encodes whether the 2 values are equal, less, greater, or unordered and can return different types depending on the strictness of the comparison. [3] The name's origin is due to it reminding Randal L. Schwartz of the spaceship in an HP BASIC Star Trek game. [4]

    The language B introduced the use of == with this meaning, which has been copied by its descendant C and most later languages where = means assignment. Some languages additionally feature the "spaceship operator", or three-way comparison operator, <=>, to determine whether one value is less than, equal to, or greater than another.

That is, whatever A and B are, A ≤ B is equivalent to A < B or A = B. 2. Between two groups, may mean that the first one is a subgroup of the second one. ≥ 1. Means "greater than or equal to".

    A snippet of Python code with keywords highlighted in bold yellow font. The syntax of the Python programming language is the set of rules that defines how a Python program will be written and interpreted (by both the runtime system and by human readers). The Python language has many similarities to Perl, C, and Java. However, there are some ...

    Many other notations are also in use. In some languages, the symbol used is regarded as an operator (meaning that the assignment statement as a whole returns a value). Other languages define assignment as a statement (meaning that it cannot be used in an expression).
