A plus sign after a number breaks default numerical sorting if it is in one of the first 5 cells in a column. A plus sign in an otherwise empty cell breaks default numerical sorting of a column. That is if the cell is one of the first 5 cells in the column. You can also use 2 columns for a range if you want to sort by either the lower or upper ...
Note how the use of A[i][j] with multi-step indexing as in C, as opposed to a neutral notation like A(i,j) as in Fortran, almost inevitably implies row-major order for syntactic reasons, so to speak, because it can be rewritten as (A[i])[j], and the A[i] row part can even be assigned to an intermediate variable that is then indexed in a separate expression.
Block sort begins by performing insertion sort on groups of 16–31 items in the array. Insertion sort is an O(n 2) operation, so this leads to anywhere from O(16 2 × n/16) to O(31 2 × n/31), which is O(n) once the constant factors are omitted. It must also apply an insertion sort on the second internal buffer after each level of merging is ...
In a database, a table is a collection of related data organized in table format; consisting of columns and rows.. In relational databases, and flat file databases, a table is a set of data elements (values) using a model of vertical columns (identifiable by name) and horizontal rows, the cell being the unit where a row and column intersect.

One implementation can be described as arranging the data sequence in a two-dimensional array and then sorting the columns of the array using insertion sort. The worst-case time complexity of Shellsort is an open problem and depends on the gap sequence used, with known complexities ranging from O ( n 2 ) to O ( n 4/3 ) and Θ( n log 2 n ).
Timsort is a hybrid, stable sorting algorithm, derived from merge sort and insertion sort, designed to perform well on many kinds of real-world data. It was implemented by Tim Peters in 2002 for use in the Python programming language. The algorithm finds subsequences of the data that are already ordered (runs) and uses them to sort the ...
Such a component or property is called a sort key. For example, the items are books, the sort key is the title, subject or author, and the order is alphabetical. A new sort key can be created from two or more sort keys by lexicographical order. The first is then called the primary sort key, the second the secondary sort key, etc.
See Help:Sortable tables#Numerical sorting problems and meta:Help:Sorting#Sort modes Equal rank If you simply code as the second parameter an indicator that two items are equally ranked, e.g. "4=", the template interpreter will treat this as an additional parameter (i.e. parameter 4, which it will then not use).
