1078 Hashing (25 分)   The task of this problem is simple: insert a sequence of distinct positive integers into a hash table, and output the positions of the input numbers. The hash function is defined to be ( where TSize is the maximum size of the ha…

题目:https://pintia.cn/problem-sets/994805342720868352/problems/994805389634158592 题意: 给定哈希表的大小和n个数,使用平方探测法解决冲突,为每个数在哈希表中的位置. 如果给定的哈希表的大小不是质数,将其改为最小的比他大的质数. 思路: 比较基础的题目.有两个要注意的点! 1.初始化notprime数组时,需要注意1,也不是质数.特殊处理notprime[1] = true 2.注意考虑prob的边界,应该是哈希表的…
