1002 A+B for Polynomials (25)（25 分）提问

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 a~N1~ N2 a~N2~ ... NK a~NK~, where K is the number of nonzero terms in the polynomial, Ni and a~Ni~ (i=1, 2, ..., K) are the exponents and coefficients, respectively. It is given that 1 <= K <= 10，0 <= NK < ... < N2 < N1 <=1000.

Output

For each test case you should output the sum of A and B in one line, with the same format as the input. Notice that there must be NO extra space at the end of each line. Please be accurate to 1 decimal place.

Sample Input

2 1 2.4 0 3.2
2 2 1.5 1 0.5

Sample Output

3 2 1.5 1 2.9 0 3.2

代码：

#include
int main(){
	double a[1010]={0};
	int count=0;
	int t=2;
	while(t--){
		int m;
		int e;
		double k;//指数，系数 
		scanf("%d",&m);
		for(int i=0;i=0;i--){
		if(a[i]!=0){
			printf(" %d %.1f",i,a[i]);
		}
	}
	return 0;
}

这个题目需要注意的点：

1：不能统统变量定义都为int啊，有浮点运算的，都必须是double型。而且double的输入应该是%lf，我起初写的是%f然后错了，细节细节。。。。。

2:最后一个测试点格式错误，一定要注意，所有的多项式的系数对应相加后都为0，所以为0项多项式，所以你的代码里面这个0的输出后面不能跟空格啊，有就错了。
