NAME
    Array::Sample::SimpleRandom - Sample elements randomly (with or without
    replacement)

VERSION
    This document describes version 0.002 of Array::Sample::SimpleRandom
    (from Perl distribution Array-Sample-SimpleRandom), released on
    2022-05-20.

SYNOPSIS
     use Array::Sample:: qw(sample_simple_random_with_replacement sample_simple_random_no_replacement);

     sample_simple_random_with_replacement([0,1], 1); => (0)
     sample_simple_random_with_replacement([0,1], 3); => (0,1,0)

     sample_simple_random_no_replacement([0,1,2,3,4], 1); => (3)
     sample_simple_random_no_replacement([0,1,2,3,4], 3); => (2,1,4)
     sample_simple_random_no_replacement([0,1,2,3,4], 7); => (3,4,2,1,0)

DESCRIPTION
FUNCTIONS
    All functions are not exported by default, but exportable.

  sample_simple_random_with_replacement
    Syntax: sample_simple_random_with_replacement(\@ary, $n [ , \%opts ]) =>
    list

    Options:

    *   pos => bool

        If set to true, will return positions instead of the elements.

    The function takes an array reference ("\@ary") and number of samples to
    take ($n). It will take samples at random position. An element can be
    picked more than once.

  sample_simple_random_no_replacement
    Syntax: sample_simple_random_no_replacement(\@ary, $n [ , \%opts ]) =>
    list

    Options:

    *   pos => bool

        If set to true, will return positions instead of the elements.

    The function takes an array reference ("\@ary") and number of samples to
    take ($n). It will take samples at random position. An element can only
    be epicked once. If $n is larger than the number of elements in the
    array, only that many elements will be taken.

    The implementation constructs a (shallow) copy of the array then remove
    elements randomly from the copy-array until the number of requested
    samples are met. There is another implementation that avoids creating a
    copy but scans the array once; see Array::Sample::SimpleRandom::Scan.

CONTRIBUTING
    To contribute, you can send patches by email/via RT, or send pull
    requests on GitHub.

    Most of the time, you don't need to build the distribution yourself. You
    can simply modify the code, then test via:

     % prove -l

    If you want to build the distribution (e.g. to try to install it locally
    on your system), you can install Dist::Zilla,
    Dist::Zilla::PluginBundle::Author::PERLANCAR, and sometimes one or two
    other Dist::Zilla plugin and/or Pod::Weaver::Plugin. Any additional
    steps required beyond that are considered a bug and can be reported to
    me.
