type in an application. Each element in an array is indexed numerically, which makes locating data within a program orderly and straightforward. Usually, indexes start with the number 0, so that the first element is numbered 0, the second numbered 1, etc. This is called zero-based indexing....

In database indexing, a block is used to organize data for faster searching. Indexes are often created on specific columns, which point to a block where the corresponding data is stored. This speeds up data retrieval by minimizing the need to scan through the entire dataset. ...
Size is fixed:An array has a defined size, therefore it is static in that sense. An array’s assigned memory cannot be increased or decreased. This prevents the storage of additional data in the event of a need. If an array is given less memory than is necessary, this may occasionally ...
a descending index can improve performance for queries that retrieve the most recent or highest values. however, it is important to consider the specific use case and consult the database documentation for optimal indexing strategies. can i sort an array in descending order using built-in functions...
example_array[-1] 8 Python supports more advanced indexing through its slice notation. Slicing allows you to select a range of elements from an array. The syntax for slice notation is the following: [start:stop:step] start defines the first index of the range and stop defines the last....
