When a number is not a prime, this number can be factored into two factors namelyaandbi.e.number= a * b.If bothaandbwere greater than the square root ofn,a*bwould be greater thann. So at least one of those factors must be less than or equal the square root of a number and to...

本次解题使用的开发工具是eclipse,jdk使用的版本是1.8,环境是win7 64位系统,使用Java语言编写和测试。 02 第一种解法 第一步,需要先计算出整数的二进制数中1的个数,借助包装类Integer的bitCount方法来完成。 第二步,判断第一步获取的1的个数是否是一个素数,通过一个辅助方法来实现,如果是素数,计数count加1。
Here, in this tutorial you will learn C++ program to check whether the entered number is a prime number or not by using the if-else statements.
