The number of different Cartesian trees of s nodes is C s, the s 'th Catalan number; Therefore, the number of different Cartesian trees for the blocks is in the range of 4 s; For every such tree, the possible result for all queries need to be stored. This comes down to s 2 or O (log 2 n) entries. This means the overall size of the table is O (n).
These two one-sided range top-k queries return the top-(/) most frequent elements in each of their respective ranges in (/) time. These frequent elements make up the set of candidates for τ {\displaystyle \tau } -majorities in A [ i . . j ] {\displaystyle A[i..j]} in which there are O ( 1 / τ ) {\displaystyle O(1/\tau )} candidates some of ...
In the case of an integer, the variable definition is restricted to whole numbers only, and the range will cover every number within its range (including the maximum and minimum). For example, the range of a signed 16-bit integer variable is all the integers from −32,768 to +32,767.
Tukey's range test, also known as Tukey's test, Tukey method, Tukey's honest significance test, or Tukey's HSD (honestly significant difference) test, [1] is a single-step multiple comparison procedure and statistical test.
First, create a tree using the ranges for the y-coordinate. Now, for each node in the tree, add another interval tree on the x-ranges, for all elements whose y-range is the same as that node's y-range. The advantage of this solution is that it can be extended to an arbitrary number of dimensions using the same code base.
Bucket sort may be used in lieu of counting sort, and entails a similar time analysis. However, compared to counting sort, bucket sort requires linked lists, dynamic arrays, or a large amount of pre-allocated memory to hold the sets of items within each bucket, whereas counting sort stores a single number (the count of items) per bucket.

Python supports normal floating point numbers, which are created when a dot is used in a literal (e.g. 1.1), when an integer and a floating point number are used in an expression, or as a result of some mathematical operations ("true division" via the / operator, or exponentiation with a negative exponent).
Counting sort uses a table of counters in place of a table of buckets, to determine the number of items with each key. Then, a prefix sum computation is used to determine the range of positions in the sorted output at which the values with each key should be placed.
