已知某哈希表的装载因子小于1，哈希函数

H(key)为关键字(标识符)的第一个字母在字母表中

的序号，处理冲突的方法为线性探测开放定址法。

试编写一个按第一个字母的顺序输出哈希表中所有

关键字的算法。-Known load factor of a hash table is less than 1, the hash function H (key) for the keywords (identifiers) of the first letter of the alphabet in the serial number, dealing with the conflict detection for the linear open addressing method . Try to write a letter by the first order of output of the hash table algorithm for all keywords.
