仅有两个要注意的点: 如果系数为0,则不输出,所以输入结束以后要先遍历确定系数不为零的项的个数 题目最后一句,精确到小数点后一位,如果这里忽略了,会导致样例1,3,4,5都不能通过…

1002. A+B for Polynomials (25) This time, you are supposed to find A+B where A and B are two polynomials. Input Each input file contains one test case. Each case occupies 2 lines, and each line contains the information of a polynomial: K N1 aN1 N2 aN…

[题目]B. GCD of Polynomials [题意]给定n,要求两个最高次项不超过n的多项式(第一个>第二个),使得到它们GCD的辗转次数为n.n<=150. [算法]构造 [题解]辗转n次是最坏情况——每次辗转至少会使被模数的最高次项变到模数的最高次项-1,也就是必须构造两个多项式满足这种最坏情况. eg.n=5,(5,4),(4,3),(3,2),(2,1),(1,0),(0,0). 为了构造最坏情况,考虑模仿斐波那契数列进行构造: p(0)=1,p(1)=x,p(n)=x*p(n…

这道题算有点难,心目中理想的难度. 不能前怕狼后怕虎,一会担心超时,一会又担心内存过大,直接撸 将三部分分别保存到vector 有意思的在于输出 分别输出第一个的add和num 中间输出nextadd ,换行,add,num 最后输出尾元素的next为-1 #include<iostream> #include<stdio.h> #include<map> #include<string> #include<algorithm> #include…
