PJ考试可能会用到的数学思维题选讲 by Pleiades_Antares 是学弟学妹的讲义--然后一部分题目是我弄的一部分来源于洛谷用户@ 普及组的一些数学思维题,所以可能有点菜咯别怪我 OI中的数学题--你会你就能做,不会做就是真的做不出来QAQ 鲁迅曾说:一入数学深似海,从此AC是路人. 一些会说到的题目:(都是洛谷编号) 这些题目全都是原来NOIP考过的真题喔 1010 1014 1029 1035 1045 1075 1012 1351 2119 ok咱们开始说 第一题,洛谷P1010…

最近以C#为例,学习了程序设计基础,其中涉及到一些数学思维,我们可以巧妙的将这些逻辑问题转换为代码,交给计算机运算. 现将经常会使用到的基础函数做一总结,供大家分享.自己备用. 1.判断一个数是否为奇数 定义:整数中,能被2整除的数是偶数,不能被2整除的数是奇数 思路点:n%2!=0则为奇数 /// <summary> /// 判断一个整数是不是奇数 /// </summary> /// <param name="n">要判断的整数</para…
