【nc】 Arrays&Hashing 7/9 Encode and Decode Strings 编码解码字符串 271 ==== 思路: 1 编码可以编码为下面形式: 数量#字符串数量#字符串的形式 2 然后进行解码,while ( i < s.length),向下查找匹配每个字符串,找到对应的s,推入到数组中,并返回结果
Hashing is useful for many different types of operations, including lookup, insert, delete, and find. By using a hash table, these operations can be performed in constant time (O(1)), meaning the time taken does not change with the size of the table (in the average case). Hashi...
Since location 1 has different values for hash1 and hash2 we can conclude the arrays are not the same. So, what we actually did using hashing is to check whether all the unique elements in the two arrays are exactly the same or not and if the same then their frequencies are the same...
$arr1=[10,20,30];$arr2=array("one"=>1,"two"=>2,"three"=>3);var_dump($arr1[1]);var_dump($arr2["two"]);?> Output It will produce the following output − int(20) int(2) We shall explore the types of PHP arrays in more details in the subsequent chapters. ...
