[简单数学]ZOJ 2969 Easy Task

    给定系数，求其导数，很简单的。。。

#include <iostream>#include <cstdio>#include <cstring>using namespace std;int main(){    int F[200], f[200], cas, m;    scanf("%d", &cas);    while(cas--)    {        memset(F, 0, sizeof(F));        memset(f, 0, sizeof(f));        int cnt = 0;        scanf("%d", &m);        for(int i = m; i >=0; i--)        {            scanf("%d", &F[i]);            if(i != 0)                f[i] = F[i] * i;            if(f[i]) cnt ++;        }        if(cnt == 0)            printf("0");        else        {            for(int i = m; i >= 1; i--)            {                printf("%d", f[i]);                if(i != 1)                    printf(" ");            }        }        printf("\n");    }    return 0;}
