数组开大点试试

@[beacon](/space/show?uid=75303) 还是不行

@[Kristella](/space/show?uid=86623) 一个整型变量*1.2会向下取整printf("%d",sum1*1.2+sum2);
应改成
double t=(double)sum1;
printf("%.0lf",t*1.2+t);

请无视第1个！

还有，
```
else if(a[i]+save<a[i+1])
{
printf("%d",-i);
break;
}
```
break应改成
```
else if(a[i]+save<a[i+1])
{
printf("%d",-i);
return 0;
}
```
