题目描述:
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 aN2 ... NK aNK, where K is the number of nonzero terms in the polynomial, Ni and aNi (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
参考代码:
分析:给出俩个多项式的指数和系数,没有给出基数,只要将指数相同的多项式进行系数相加即可。输出时按照指数从高到低的顺序输出。
最后输出的结果原先是这样输出:
[cpp] view plaincopyprint printf(" %d% .1lf",i,input[i]);
printf(" %d% .1lf",i,input[i]); 但是会有一组数据不通过。后来改为如下: [cpp] view plaincopyprint cout<
#include
#include
#include
using namespace std;
#define max 1000
double input[max + 1];
int main()
{
int k,count;
int i,expo;
double coef;
cin>>k;
memset(input,0,sizeof(input));
for(i=0; i>expo>>coef;
input[expo] += coef;
}
cin>>k;
for(i=0; i>expo>>coef;
input[expo] += coef;
}
count = 0;
for(i=1000; i>=0; i--)
if(input[i] != 0) count++;
cout<=0; i--)
if(input[i] != 0.0)
{
cout<
