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.
Use of a user-defined function sq(x) in Microsoft Excel. The named variables x & y are identified in the Name Manager. The function sq is introduced using the Visual Basic editor supplied with Excel. Subroutine in Excel calculates the square of named column variable x read from the spreadsheet, and writes it into the named column variable y.
One such method is the use of weak references, while another involves using a mark-sweep algorithm that gets called infrequently to clean up. In a concurrent setting, all updates of the reference counts and all pointer modifications must be atomic operations, which incurs an additional cost.
