1009ProductofPolynomials题目大意:计算多项式A×B的结果,结果的输出形式与AB输入形式要一样。解题思路:开两个数组模拟即可,本题有一点需要注意,就是系数为0的项不计入数量并且也不输出,否则第一个测试点无法通过,代码如下:#include#include#include#include#include#include#include#include#include#inclu

和1002很像嗯,所以又看了一下午才把题看懂就是第一行的每一项都与第二行的每一项指数相加,系数相乘然后再和1002一样指数相同的合并题目做起来很简单第一遍做完,样例也顺利过了提交10分,,,emmmm这次的0都有注意啊,,输出格式也没错,,没啥能改的地方啊???网上的代码有的都和我一样啊就是数组名字不一样难道是数组大小的事?1000->2000没过,,而且变成了5分,那就说明是数组大小的问题了照着

今天突然对pat的练习题来了兴趣,加上宿舍大腿的鼓舞,趁热打铁写第二题,A+BforPolynomials,不多说,先上题。先大致说一下思路吧:如果将多项式的系数和指数分开来存的话,浪费空间,增加运算时间,所以说不如只是开辟一个数组,将指数作为数组下标来存储相应的系数,最后扫描的时候,根据数组元素是否为零来进行下标和数值输出。值得一提的是,由于数组的输出格式要求严格,所以需要引起注意。以下是自己写

其实这个代码还是有问题的,怎么测试点就全通过了呢,就是最终输出的count值有问题。。。。题目地址这个题目花费了一些时间调试,因为思考的不全面,被题目描述所引导了,一直以为多项式的系数只会给正数,最后看到别人提的问题才意识到这一点。因为最后的输出条件开始是用和是否为0作为判断条件的。还有就是精度问题,中间fabs那段代码参考了别人的代码,不然一直有两个测试点过不去。#include#include

1.题意给两个多项式,把它们加起来样例分析:A多项式212.403.2第一个2指得是2个非0系数项然后的两个数,1是项数,2.4是系数最后两个数,0是项数,3.2是系数所以就有f(x)=2.4x+3.2B多项式221.510.5f(x)=1.5x²+0.5x所以它们的和就是F(x)=1.5x²+2.9x+3.2,然后我们先输出总项数,再依次输出这个多项式的项数和系数2.思路用数组下标存项数,数组值
