示例1: Main
/* 4 Implement the data structure "hash table" in a class HashTable<K,T>. Keep the data in array of
* lists of key-value pairs (LinkedList<KeyValuePair<K,T>>[]) with initial capacity of 16. When the
* hash table load runs over 75%, perform resizing to 2 times larger capacity. Implement the following
* methods and properties: Add(key, value), Find(key)value, Remove( key), Count, Clear(), this[], Keys.
* Try to make the hash table to support iterating over its elements with foreach.
* */
