Return the minimum and maximum values of the input sequence.
Note that complex values are compared lexicographically.
However, when the input sequence is a scalar string, the individual characters comprise the elements/values that are compared against each other.
See pm_complexCompareLex and pm_container for more information on the relevant lexical comparison operators.
Also, note that a logical .false. is less than .true. in this module.

- Bug:
Status: Unresolved
Source: Intel Classic Fortran Compiler ifort version 2021.8.0 20221119, Intel LLVM Fortran Compiler ifx version 2023.0.0 20221201
Description: The Intel Classic Fortran Compiler ifort and Intel LLVM Fortran Compiler ifx as of the specified versions above cannot find the minimum and maximum of a constant empty array of type character.
This has prevented the definition of the constants COL_SEQ_BEG and COL_SEQ_END in the module pm_str which are also needed in this module.
For example, the following code yields an Internal Compiler Error:
character(1), parameter :: ARRAY_EMPTY(0) = [character(1)::]
character(*), parameter :: COL_SEQ_BEG = minval(ARRAY_EMPTY,1)
end
catastrophic error: **Internal compiler error: segmentation violation signal raised**
Please report this error along with the circumstances in which it occurred in a Software Problem Report.
Note: File and line given may not be explicit cause of this error.
Remedy (as of ParaMonte Library version 2.0.0): For now, the empty arrays are constructed dynamically within the routines of this module.
- Todo:
- Critical Priority: The dynamic
character allocation due to the bug described above must be eliminated within the implementation of this module as soon as the Intel compilers bugs are resolved.
- Todo:
- Low Priority: This generic interface can be expanded to include the possibility of passing user-defined custom comparison.
