https://www.patest.cn/contests/gplt/L2-018 题意:模拟多项式除法. 题解:短除法,初中奥数老师,高中数学老师,高数老师都讲过2333. 模拟之前,关于保存 多项式的方法.考虑到系数可能很分散(1~1e9),直接用map存(map基本就是为多项式加减法定制的) 模拟的时候,就是数学课上短除法的算法,注意一下循环终止条件及其控制:当多项式A的最高次系数小于B的时,除不下去,此时A已然为余数. 模拟完,输出 .本来用stack只是因为auto:t不能逆向输出,

7-10 多项式A除以B (25分)   这仍然是一道关于A/B的题,只不过A和B都换成了多项式.你需要计算两个多项式相除的商Q和余R,其中R的阶数必须小于B的阶数. 输入格式: 输入分两行,每行给出一个非零多项式,先给出A,再给出B.每行的格式如下: N e[1] c[1] ... e[N] c[N]   其中N是该多项式非零项的个数,e[i]是第i个非零项的指数,c[i]是第i个非零项的系数.各项按照指数递减的顺序给出,保证所有指数是各不相同的非负整数,所有系数是非零整数,所有整数在整型范围

给定一个插入序列就可以唯一确定一棵二叉搜索树.然而,一棵给定的二叉搜索树却可以由多种不同的插入序列得到. 例如分别按照序列{2, 1, 3}和{2, 3, 1}插入初始为空的二叉搜索树,都得到一样的结果.于是对于输入的各种插入序列,你需要判断它们是否能生成一样的二叉搜索树. 输入格式: 输入包含若干组测试数据.每组数据的第1行给出两个正整数N(≤10)和L,分别是每个序列插入元素的个数和需要检查的序列个数. 第2行给出N个以空格分隔的正整数,作为初始插入序列.最后L行,每行给出N个插入的元素,属
