Detailed Description

Generate and return the Modified rank of the input scalar string or contiguous array of rank 1 in ascending order or in the order specified by the input procedure isSorted() using the Quicksort algorithm such that array(rank) will be in ascending order (or in the requested order as specified by isSorted().

This kind of ranking of values is widely known as Modified Competition (1334) ranking.
Sometimes, competition ranking is done by leaving the gaps in the ranking numbers before the sets of equal-ranking items (rather than after them as in Standard Competition ranking).
The number of ranking numbers that are left out in this gap remains one less than the number of items that compared equal.
Equivalently, the ranking number of each item is equal to the number of items ranked equal to it or above it.
This ranking ensures that a competitor only comes second if they score higher than all but one of their opponents, third if they score higher than all but two of their opponents, etc.
Thus if A ranks ahead of B and C (which compare equal) which are both ranked head of D, then A gets ranking number 1 (first), B gets ranking number 3 (joint third), C also gets ranking number 3 (joint third) and D gets ranking number 4 (fourth).
In this case, nobody would get ranking number 2 (second) (left as a gap).
That is, if A < B == C < D, then the sequence ABCD has the Modified Competition ranking 1334.

Parameters

[in]

array

: The input contiguous array of rank 1 of either

type css_pdt (parameterized container of string of kind any supported by the processor (e.g., SK, SKA, SKD , or SKU)) or,
type css_type (container of string of default kind SK) or,
type character of kind any supported by the processor (e.g., SK, SKA, SKD , or SKU) of arbitrary length type parameter or,
type integer of kind any supported by the processor (e.g., IK, IK8, IK16, IK32, or IK64) or,
type logical of kind any supported by the processor (e.g., LK) or,
type complex of kind any supported by the processor (e.g., CK, CK32, CK64, or CK128) or,
type real of kind any supported by the processor (e.g., RK, RK32, RK64, or RK128),

or,

a scalar of type character of kind any supported by the processor (e.g., SK, SKA, SKD , or SKU) of arbitrary length type parameter,

whose elements rankings will be computed and returned.

[out] rank : The output contiguous array of rank 1 of type integer of default kind IK containing the ranks of the corresponding elements of array.
The size of rank must match that of array (or its length type parameter if array is a scalar string).
Read rank(i) as the Modified rank of the ith element of array.

isSorted

: The external user-specified function that takes two input scalar arguments of the same type and kind as the input array.
It returns a scalar logical of default kind LK that is .true. if the first input scalar argument is sorted with respect to the second input argument according to the user-defined sorting condition within isSorted(), otherwise, it is .false..
If array is a Fortran string (i.e., a scalar character), then both input arguments to isSorted() are single character(1,SKG) where SKG is the kind of array.
The following illustrates the generic interface of isSorted() when the rank of the input array is 1,

function isSorted(a,b) result (sorted)
    use pm_kind, only: SK, IK, LK, CK, RK
    TYPE(KIND)  , intent(in)    :: a, b
    logical(LK)                 :: sorted
end function

where TYPE(KIND) represents the type and kind of the input argument array, which can be one of the following,

use pm_container, only: css_type, css_pdt
use pm_kind, only: SK, IK, LK, CK, RK
character(*, SK)    , intent(in)    :: a, b
integer(IK)         , intent(in)    :: a, b
logical(LK)         , intent(in)    :: a, b
complex(CK)         , intent(in)    :: a, b
real(RK)            , intent(in)    :: a, b
type(css_type)      , intent(in)    :: a, b
type(css_pdt(SK))   , intent(in)    :: a, b

where the kinds SK, IK, LK, CK, RK, can refer to any kind type parameter that is supported by the processor.
The following illustrates the generic interface of isSorted() when the input array is a scalar string,

function isSorted(a,b) result (sorted)
    character(1,SKG), intent(in)    :: a, b
    logical(LK)                     :: sorted
end function

where SKG represents the kind of the input string argument array.
This user-defined equivalence check is extremely useful where a user-defined sorting criterion other than simple ascending order is needed, for example, when the case-sensitivity of an input string or array of strings is irrelevant or when sorting of the absolute values matters excluding the signs of the numbers, or when descending order is desired.
In such cases, user can define a custom sorting condition within the user-defined external function isSorted to achieve the goal.
(optional, the default sorting condition is ascending order, that is a < b.)

Returns: rank(1:size(array) : The output contiguous array of rank 1 of type integer of default kind IK containing the ranks of the corresponding elements of array.
The size of rank matches that of array (or its length type parameter if array is a scalar string).
Read rank(i) as the Modified rank of the ith element of array.

Definition: pm_arrayRank.F90:134

Warning: Note that the definition of isSorted(), if present, must be such that isSorted() .and. .not. isSorted() is equivalent to an equality check for two elements of the input array. This equality check is used to identify ties within the Modified ranking of the input array.; The pure procedure(s) documented herein become impure when the ParaMonte library is compiled with preprocessor macro CHECK_ENABLED=1.
By default, these procedures are pure in release build and impure in debug and testing builds.; The procedures under this generic interface are always impure when the input argument isSorted is present.

Test:: test_pm_arrayRank

Bug:: Status: Unresolved
Source: Intel Classic Fortran Compiler ifort version 2021.5
Description: See pm_arraySplit for the description of a relevant bug in PDT name aliasing when compiled with Intel ifort 2021.5 that also applies to this module.
Remedy (as of ParaMonte Library version 2.0.0): See pm_arraySplit for the remedy.

Todo:: Low Priority: The current bypass for the PDT name aliasing bug can be reverted back to PDT name aliasing once the ifort bug is resolved.

Todo:: Low Priority: A test should be implemented for arrays of size that can be represented only by an IKD integer.
