Range queries are unusual because it is not generally known in advance how many entries a range query will return, or if it will return any at all.
This contrasts with other range query problems, such as the range minimum query which have solutions offering constant time query time and linear space. This is due to the hardness of the mode problem, since even if we know the mode of A [ i : j ] {\displaystyle A[i:j]} and the mode of A [ j + 1 : k ] {\displaystyle A[j+1:k]} , there is no ...

Manipulation of persistent database objects, e.g., tables or stored procedures, via the SQL schema statements, [3] rather than the data stored within them, is considered to be part of a separate data definition language (DDL).
In computer science, the range query problem consists of efficiently answering several queries regarding a given interval of elements within an array. For example, a common task, known as range minimum query , is finding the smallest value inside a given range within a list of numbers.
