******************************************************************************
**
** This file contains code to implement the percentile(Y,P) SQL function
** and similar as described below:
**
**   (1)  The percentile(Y,P) function is an aggregate function taking
**        exactly two arguments.
**
**   (2)  If the P argument to percentile(Y,P) is not the same for every
**        row in the aggregate then an error is thrown.  The word "same"
**        in the previous sentence means that the value differ by less

**
**  (12)  The percentile(Y,P) is implemented as a single C99 source-code
**        file that compiles into a shared-library or DLL that can be loaded
**        into SQLite using the sqlite3_load_extension() interface.
**
**  (13)  A separate median(Y) function is the equivalent percentile(Y,50).
**
**  (14)  A separate percentile_cont(Y,P) function is equivalent to
**        percentile(Y,P/100.0).  In other words, the fraction value in
**        the second argument is in the range of 0 to 1 instead of 0 to 100.
**
**  (15)  A separate percentile_disc(Y,P) function is like
**        percentile_cont(Y,P) except that instead of returning the weighted
**        average of the nearest two input values, it returns the next lower
**        value.  So the percentile_disc(Y,P) will always return a value
**        that was one of the inputs.
**
**  (16)  All of median(), percentile(Y,P), percentile_cont(Y,P) and
**        percentile_disc(Y,P) can be used as window functions.
**
** Differences from standard SQL:
**
**  *  The percentile_cont(X,P) function is equivalent to the following in
**     standard SQL:
**
**         (percentile_cont(P) WITHIN GROUP (ORDER BY X))
**
**     The SQLite syntax is much more compact.  The standard SQL syntax
**     is also supported if SQLite is compiled with the
**     -DSQLITE_ENABLE_ORDERED_SET_AGGREGATES option.
**
**  *  No median(X) function exists in the SQL standard.  App developers
**     are expected to write "percentile_cont(0.5)WITHIN GROUP(ORDER BY X)".
**
**  *  No percentile(Y,P) function exists in the SQL standard.  Instead of
**     percential(Y,P), developers must write this:
**     "percentile_cont(P/100.0) WITHIN GROUP (ORDER BY Y)".  Note that
**     the fraction parameter to percentile() goes from 0 to 100 whereas
**     the fraction parameter in SQL standard percentile_cont() goes from
**     0 to 1.
**
** Implementation notes as of 2024-08-31:
**
**  *  The regular aggregate-function versions of these routines work
**     by accumulating all values in an array of doubles, then sorting
**     that array using quicksort before computing the answer. Thus
**     the runtime is O(NlogN) where N is the number of rows of input.
**
**  *  For the window-function versions of these routines, the array of
**     inputs is sorted as soon as the first value is computed.  Thereafter,
**     the array is kept in sorted order using an insert-sort.  This
**     results in O(N*K) performance where K is the size of the window.
**     One can imagine alternative implementations that give O(N*logN*logK)
**     performance, but they require more complex logic and data structures.
**     The developers have elected to keep the asymptotically slower
**     algorithm for now, for simplicity, under the theory that window
**     functions are seldom used and when they are, the window size K is
**     often small.  The developers might revisit that decision later,
**     should the need arise.

** DEPRECATED
**
** These functions are [deprecated].  In order to maintain
** backwards compatibility with older code, these functions continue

**   for the current request. If pLocale and nLocale are both 0, then the
**   tokenizer should use its default locale. Otherwise, pLocale points to
**   an nLocale byte buffer containing the name of the locale to use as utf-8
**   text. pLocale is not nul-terminated.
**
** FTS5_TOKENIZER
**
** There is also an fts5_tokenizer object. This is an older, deprecated,
** version of fts5_tokenizer_v2. It is similar except that:
**
**  <ul>
**    <li> There is no "iVersion" field, and
**    <li> The xTokenize() method does not take a locale argument.
**  </ul>
**
** Legacy fts5_tokenizer tokenizers must be registered using the
** legacy xCreateTokenizer() function, instead of xCreateTokenizer_v2().
**
** Tokenizer implementations registered using either API may be retrieved
** using both xFindTokenizer() and xFindTokenizer_v2().
**
** SYNONYM SUPPORT
**
**   Custom tokenizers may also support synonyms. Consider a case in which a
**   user wishes to query for a phrase such as "first place". Using the
**   built-in tokenizers, the FTS5 query 'first + place' will match instances

/*
** CAPI3REF: Deprecated Functions
** DEPRECATED
**
** These functions are [deprecated].  In order to maintain
** backwards compatibility with older code, these functions continue

**   for the current request. If pLocale and nLocale are both 0, then the
**   tokenizer should use its default locale. Otherwise, pLocale points to
**   an nLocale byte buffer containing the name of the locale to use as utf-8
**   text. pLocale is not nul-terminated.
**
** FTS5_TOKENIZER
**
** There is also an fts5_tokenizer object. This is an older, deprecated,
** version of fts5_tokenizer_v2. It is similar except that:
**
**  <ul>
**    <li> There is no "iVersion" field, and
**    <li> The xTokenize() method does not take a locale argument.
**  </ul>
**
** Legacy fts5_tokenizer tokenizers must be registered using the
** legacy xCreateTokenizer() function, instead of xCreateTokenizer_v2().
**
** Tokenizer implementations registered using either API may be retrieved
** using both xFindTokenizer() and xFindTokenizer_v2().
**
** SYNONYM SUPPORT
**
**   Custom tokenizers may also support synonyms. Consider a case in which a
**   user wishes to query for a phrase such as "first place". Using the
**   built-in tokenizers, the FTS5 query 'first + place' will match instances
**   of "first place" within the document set, but not alternative forms
