PAT甲级1002A+BforPolynomials(25分)题目:解题思路:这是一题多项式相加的问题,主要考察对于输出格式的理解与应用,以及数组的上边界,先将数据读入,因为是两行而且行间有空格,但空格不必读入,故使用scanf来读入,读入double类型时用%lf,而输出时用%.1f,用来保留一位小数。看清楚,不是lf而是1f(哈哈哈,检查了半天没检查出来,巨弱一枚),最后输出时候注意从maxn

这道题我一开始的思路就是混乱的,居然写出了三层嵌套循环...不过幸好后来看了柳神的思路分析,才发现之前做过类似解法的题目,但这个思路还是没有在脑子里形成一个套路,因此借助这道题来总结一下:涉及到同项或同类型累加或各种计算问题时,建立数组并进行同项操作是一个非常简单的方法。除此之外还有很多小问题,比如第一次提交时居然没看清题目要求输出多项式非零项数导致结果错误等,也是平时做题时需要注意的问题。#in

题意就是给你一个多项式的每个系数问你改变一个系数使Q(2)=0,需要改变几次思路:就是先把他变成二进制思考,然后这个数的第i项二进制后i位是0,所以求和的时候,如果太后位为1的话,后面的和是无法消去这个1的,结果就不是0了。然后每次检测一下最后一位是否为1,是的话到这一位为止前面的都可以更改。然后如果后面是0,就可以右移一位,也就是除以二,然后接着计算前缀和就是了。后缀和处理类似,只是把判断最后一
