  2. Increment and decrement operators - Wikipedia

    en.wikipedia.org/wiki/Increment_and_decrement...

    The post-increment and post-decrement operators increase (or decrease) the value of their operand by 1, but the value of the expression is the operand's value prior to the increment (or decrement) operation. In languages where increment/decrement is not an expression (e.g., Go), only one version is needed (in the case of Go, post operators only).

  3. Unary operation - Wikipedia

    en.wikipedia.org/wiki/Unary_operation

    In mathematics, a unary operation is an operation with only one operand, i.e. a single input. [1] This is in contrast to binary operations, which use two operands. [2] An example is any function ⁠: ⁠, where A is a set; the function ⁠ ⁠ is a unary operation on A.

  4. P versus NP problem - Wikipedia

    en.wikipedia.org/wiki/P_versus_NP_problem

    Just as the class P is defined in terms of polynomial running time, the class EXPTIME is the set of all decision problems that have exponential running time. In other words, any problem in EXPTIME is solvable by a deterministic Turing machine in O (2 p ( n ) ) time, where p ( n ) is a polynomial function of n .

  5. Integer overflow - Wikipedia

    en.wikipedia.org/wiki/Integer_overflow

    If the variable has a signed integer type, a program may make the assumption that a variable always contains a positive value. An integer overflow can cause the value to wrap and become negative, which violates the program's assumption and may lead to unexpected behavior (for example, 8-bit integer addition of 127 + 1 results in −128, a two's ...

  6. Python syntax and semantics - Wikipedia

    en.wikipedia.org/wiki/Python_syntax_and_semantics

    In Python, everything is an object, even classes. Classes, as objects, have a class, which is known as their metaclass. Python also supports multiple inheritance and mixins. The language supports extensive introspection of types and classes. Types can be read and compared—types are instances of type. The attributes of an object can be ...

  7. Class variable - Wikipedia

    en.wikipedia.org/wiki/Class_variable

    In the above Python code, it does not provide much information as there is only class variable in the Dog class that provide the vertebrate group of dog as mammals. In instance variable, you could customize your own object (in this case, dog_1) by having one or more instance variables in the Dog class.

  8. Programmable calculator - Wikipedia

    en.wikipedia.org/wiki/Programmable_calculator

    Originally, calculator programming had to be done in the calculator's own command language, but as calculator hackers discovered ways to bypass the main interface of the calculators and write assembly language programs, calculator companies (particularly Texas Instruments) began to support native-mode programming on their calculator hardware ...

  9. DTIME - Wikipedia

    en.wikipedia.org/wiki/DTIME

    P is the smallest robust class which includes linear-time problems () (AMS 2004, Lecture 2.2, pg. 20). P is one of the largest complexity classes considered "computationally feasible". A much larger class using deterministic time is EXPTIME , which contains all of the problems solvable using a deterministic machine in exponential time .
