针对某一集体中的人名(30人)设计一哈希表，使得平均查找长度不超过2，完成相应的建表和查表程序。要求用除留余数法构造哈希函数，用补偿性线性探测法处理冲突(算法简单容易理解）-Against a group of names (30) to design a hash table, making an average to find the length of not more than 2 to complete the appropriate procedures to build tables and look-up table. Request to stay more than a few laws in addition to structural hash function, with compensatory linear detection method to deal with conflict (algorithm is simple and easy to understand)
