哈希因赋值而诞生，单词个数的统计

发布时间：2020-12-15 21:05:22 所属栏目：大数据来源：网络整理

导读：程序如下 print "Please input the namen";chomp(@words=STDIN);foreach $word(@words){$count{$word} +=1;#哈希因赋值而诞生}foreach $word(keys %count)#在这里如果写成foreach $word(sort keys %count),那么就可以对输出的信息进行排序{print "$word was

程序如下

print "Please input the namen";
chomp(@words=<STDIN>);
foreach $word(@words)
{
	$count{$word} +=1;#哈希因赋值而诞生
}
foreach $word(keys %count)#在这里如果写成foreach $word(sort keys %count),那么就可以对输出的信息进行排序
{
	print "$word was seen $count{$word} times.n";
}

以下为运行结果：

F:&;perla.pl
Please input the name
grep
thank you
thank you
how are you
my name si
hha
hha
^Z
thank you was seen 1 times.
hha was seen 2 times.
grep  was seen 1 times.
thank you  was seen 1 times.
how are you was seen 1 times.
my name si was seen 1 times.
