UVA - 10300 Ecological Premium（水题）

Problem A
Ecological Premium
Input: standard input
Output: standard output
Time Limit: 1 second
Memory Limit: 32 MB
German farmers are given a premium depending on the conditions at their farmyard. Imagine the following simplified regulation: you know the size of each farmer's farmyard in square meters and the number of animals living at it. We won't make a difference
between different animals, although this is far from reality. Moreover you have information about the degree the farmer uses environment-friendly equipment and practices, expressed in a single integer greater than zero. The amount of money a farmer receives
can be calculated from these parameters as follows. First you need the space a single animal occupies at an average. This value (in square meters) is then multiplied by the parameter that stands for the farmer's environment-friendliness, resulting in the premium
a farmer is paid per animal he owns. To compute the final premium of a farmer just multiply this premium per animal with the number of animals the farmer owns.

Input

The first line of input contains a single positive integer n (<20), the number of test cases. Each test case starts with a line containing a single integerf (0<f<20), the number of farmers in the test case. This line is
followed by one line per farmer containing three positive integers each: the size of the farmyard in square meters, the number of animals he owns and the integer value that expresses the farmers environment-friendliness. Input is terminated by end of file.
No integer in the input is greater than 100000 or less than 0.



Output

For each test case output one line containing a single integer that holds the summed burden for Germany's budget, which will always be a whole number. Do not output any blank lines.

题意：

第一行输入一个测试用例的数量m，第二行输入农夫测试用例的数量n，

接着是n行数据的输入，每行3个数据，

分别是农夫拥有的土地面积、农夫拥有的动物的数量、生态系数。

要求你计算出农夫应获得的奖金。

计算公式：

奖金 = ∑((土地面积/动物数量)×生态系数×动物数量) = ∑(土地面积×生态系统数)

			sum = 0;
			for(int i = 0; i < n; i++) {
				scanf("%d%d%d",&a,&b,&c);
				sum += a*c;
			}
			printf("%d\n",sum);
		}

	return 0;
