PAT 甲级测试题目 -- 1009 Product of Polynomials 题目链接坑点:注意系数可能为负数!!只有测试点 0 过不去可能就是因为这个!!!我最初在做这道题的时候用了两种思路,一种将保存结果的数组初始化为 0,把乘积加上去,顺便记录下最后一个指数的值。用两次 2000 次 for 循环过滤掉 0 值以及输出答案,这个代码过...

1009 Product of Polynomials 折腾半天ac不了,试了图中的例子,非零项计数出错,还以为是浮点数比较出了问题,想fabs()再与const float ZERO=1e-6比较判断是否为0 然鹅。。。 partially accected的主要原因是,只考虑了原先这个幂次的系数是不是0,没有在运算后在判断一下是否为0。
