最近开始学习python,听大家说python很强大,可以作为脚本语言,支持面向对象.面向过程编程,兼具编译性和解释性的一门动态语言.作为一名程序员有必要掌握这一门强大的"胶水语言".最近回顾了下,纪录一下运算符的优先级顺序,以下运算符的优先级依次递增: 运算符 Lambda #运算优先级最低 逻辑运算符: or 逻辑运算符: and 逻辑运算符:not 成员测试: in, not in 同一性测试: is, is not 比较: <,<=,>,>=,!=,==
题意:给出一大数K(4 <= K <= 10^100)与一整数L(2 <= L <= 106),K为两个素数的乘积(The cryptographic keys are created from the product of two primes) 问构成K的最小素数是否绝对小于L,若是,则输出BAD p,p为最小素数,否则输出GOOD; 分析:从小到大枚举1~10^6内的素数p,while(p<L)时,判断K是否能被p整除,若能则证明构成K的最小素数绝对小于L,反之则大于L
