  • sequence
  • These are input iterators (that can only be used to read a sequence of values), output iterators (that can only be used to write a sequence of values), forward iterators (that can be read, written to, and move forward), bidirectional iterators (that are like forward iterators, but can also move backwards) and random access iterators (that can move freely any number of steps in one operation). (wikipedia.org)
  • 2002
  • In early 2002, the English-language ruby-talk mailing list was receiving more messages than the Japanese-language ruby-list, demonstrating Ruby's increasing popularity in the English-speaking world. (wikipedia.org)
  • comparisons
  • This is a consequence of the limited information available through comparisons alone - or, to put it differently, of the vague algebraic structure of totally ordered sets. (wikipedia.org)
  • Non-comparison sorts (such as the examples discussed below) can achieve O(n) performance by using operations other than comparisons, allowing them to sidestep this lower bound (assuming elements are constant-sized). (wikipedia.org)
  • often
  • This can be achieved via an explicit sort operation (often an external sort), or by taking advantage of a pre-existing ordering in one or both of the join relations. (wikipedia.org)
  • This can often be replaced by input indirection or a here string, and use of cat and piping rather than input redirection is known as useless use of cat. (wikipedia.org)
  • include
  • A query includes a list of columns to include in the final result, normally immediately following the SELECT keyword. (wikipedia.org)
  • problem
  • From the beginning of computing, the sorting problem has attracted a great deal of research, perhaps due to the complexity of solving it efficiently despite its simple, familiar statement. (wikipedia.org)
  • Function
  • The letter O is used because the growth rate of a function is also referred to as order of the function. (wikipedia.org)
  • such comparison operator or comparator function must guarantee strict weak ordering. (wikipedia.org)
  • Any given basis set may be ordered so that each function can assigned a unique index. (wikipedia.org)
  • This means that a computer program for two electron integral processing can precompute the list of basis function symmetry combinations (symmetry blocks) for which integrals may be non zero and ignore all other symmetry combinations. (wikipedia.org)
  • practical
  • Matsumoto describes the design of Ruby as being like a simple Lisp language at its core, with an object system like that of Smalltalk, blocks inspired by higher-order functions, and practical utility like that of Perl. (wikipedia.org)
  • versions
  • in their place were special string literals, or "lists" of "items" delimited by commas (in later versions the "itemDelimiter" property allowed choosing an arbitrary character). (wikipedia.org)
  • records
  • Other operators have at times been suggested or implemented, such as the skyline operator (for finding only those records that are not 'worse' than any others). (wikipedia.org)
  • early
  • In a 1999 post to the ruby-talk mailing list, he describes some of his early ideas about the language: I was talking with my colleague about the possibility of an object-oriented scripting language. (wikipedia.org)
  • functions
  • Thus two types of ordering can be used: the non-zero symmetry blocks of two electron ingtegrals are ordered (the programmer is at liberty to define this order) the dimension of each block can be computed since the number of basis functions of each symmetry is known. (wikipedia.org)
