.SH "NAME"
SHARYANTO::List::Util \- List utilities
.SH "VERSION"

This document describes version 0.77 of SHARYANTO::List::Util (from Perl distribution SHARYANTO-Utils), released on 2015\-09\-04.
.SH "FUNCTIONS"
.IX Header "FUNCTIONS"
Not exported by default but exportable.
.SS "uniq_adj(@list) => \s-1LIST\s0"
.IX Subsection "uniq_adj(@list) => LIST"
Remove \fIadjacent\fR duplicates from list, i.e. behave more like Unix utility's
\&\fBuniq\fR instead of List::MoreUtils's \f(CW\*(C`uniq\*(C'\fR function, e.g.
.PP
.Vb 1
\& my @res = uniq(1, 4, 4, 3, 1, 1, 2); # 1, 4, 3, 1, 2
.Ve
.SS "uniq_adj_ci(@list) => \s-1LIST\s0"
.IX Subsection "uniq_adj_ci(@list) => LIST"
Like \f(CW\*(C`uniq_adj\*(C'\fR except case-insensitive.
.SS "uniq_ci(@list) => \s-1LIST\s0"
.IX Subsection "uniq_ci(@list) => LIST"
Like \f(CW\*(C`List::MoreUtils\*(C'\fR' \f(CW\*(C`uniq\*(C'\fR except case-insensitive.
.SS "find_missing_nums_in_seq(\s-1LIST\s0) => \s-1LIST\s0"
.IX Subsection "find_missing_nums_in_seq(LIST) => LIST"
Given a list of integers, return number(s) missing in the sequence, e.g.:
.PP
.Vb 1
\& find_missing_nums_in_seq(1, 2, 3, 4, 7, 8); # (5, 6)
.Ve
.SS "find_missing_strs_in_seq(\s-1LIST\s0) => \s-1LIST\s0"
.IX Subsection "find_missing_strs_in_seq(LIST) => LIST"
Like \f(CW\*(C`find_missing_nums_in_seq\*(C'\fR, but for strings/letters \*(L"a\*(R"..\*(L"z\*(R".
.PP
.Vb 2
\& find_missing_strs_in_seq("a", "e", "b"); # ("c", "d")
\& find_missing_strs_in_seq("aa".."zu", "zz"); # ("zv", "zw", "zx", "zy")

.IX Subsection "min_in_range($lower, $upper, @list) => $num"
Find lowest number \f(CW$num\fR in \f(CW@list\fR which still satisfies \f(CW\*(C`$lower <= $num
<= $upper\*(C'\fR. \f(CW$lower\fR and/or \f(CW$upper\fR can be undef to express no limit.

.IX Subsection "max_in_range($lower, $upper, @list) => $num"
Find highest number \f(CW$num\fR in \f(CW@list\fR which still satisfies \f(CW\*(C`$lower <= $num
<= $upper\*(C'\fR. \f(CW$lower\fR and/or \f(CW$upper\fR can be undef to express no limit.

.ie n .SS "pick(@list) => $item"
.el .SS "pick(@list) => \f(CW$item\fP"
.IX Subsection "pick(@list) => $item"
Randomly pick an item from list. It is actually simply done as:
.PP
.Vb 1
\& $_[@_ * rand]
.Ve
.PP
Example:
.PP
.Vb 2
\& pick(1, 2, 3); # => 2
\& pick(1, 2, 3); # => 1
.Ve
.ie n .SS "pick_n($n, @list) => @picked"
.el .SS "pick_n($n, \f(CW@list\fP) => \f(CW@picked\fP"
.IX Subsection "pick_n($n, @list) => @picked"
Randomly pick \f(CW\*(C`n\*(C'\fR different items from list. Note that there might still be
duplicate values in the result if the original list contains duplicates.
.PP
.Vb 4
\& pick_n(3, 1,2,3,4,5); # => (3,2,5)
\& pick_n(2, 1,2,3,4,5); # => (3,1)
\& pick_n(2, 1,1,1,1);   # => (1,1)
\& pick_n(4, 1,2,3);     # => (3,1,2)
