https://leetcode.cn/problems/prime-in-diagonal 题目描述 给你一个下标从0开始的二维整数数组nums。 返回位于nums至少一条对角线上的最大质数。如果任一对角线上均不存在质数,返回0 。 注意: 如果某个整数大于1,且不存在除1和自身之外的正整数因子,则认为该整数是一个质数。
Given two integers L and R, find the count of numbers in the range [L, R] (inclusive) having a prime number of set bits in their binary representation. (Recall that the number of set bits an integer has is the number of 1s present when written in binary. For example, 21 written in...
https://leetcode-cn.com/problems/count-primes/ 思路: 质数:指在大于 1 的自然数中,只能被 1 和自身整除的自然数。 根据质数的概念,我们首先能够想到的就是直接枚举。 对于每个数 i,我们可以枚举 [2, i-1]区间的任意一个数 j,判断 i能否被 j 整除。这里需要注意的是,这里时间复杂度最差的情况下为 ...
