给定语料文件corpus.txt，编制Perl程序，以空格为隔离，统计文件中出现的单词，输出出现次数大于10次的单词。

[解决办法]

Perl code

#!/usr/bin/env perluse strict;use warnings;my %fq;open my $fh, '<', 'corpus.txt' or die $!;while (<$fh>) {    my @words = split /\s+/;    for my $word (@words) {        $fq{$word} ? $fq{$word}++ : ($fq{$word} = 1);    }}close $fh or die $!;while (my ($k, $v) = each %fq) {    print "$k => $v\n" if ($v > 10);}
[解决办法]
#!/usr/bin/perl 
open(Out,">result.txt");
open(In,"corpus.txt");
while(<In>){
       map {++$hash{$_}} (split);
}
close In;

foreach $word (sort keys(%hash)){
       if ($hash{$word} > 10){
            print Out "$word:    $hash{$word}\n"; 
       }
}
close Out;
