Calories from Fat

Fat contains about 9 Calories/g of food energy. Protein, sugar, and starch contain about 4 Calories/g, while alcohol contains about 7 Calories/g. Although many people consume more than 50% of their total Calories as fat, most dieticians recommend that this proportion should be 30% or less. For example, in the Nutrition Facts label to the right, we see that 3g of fat is 5% of the recommended daily intake based on a 2,000 calorie diet. A quick calculation reveals that the recommended daily intake of fat is therefore 60g; that is, 540 Calories or 27% Calories from fat.

Others recommend radically different amounts of fat. Dean Ornish, for example, suggests that less than 10% of total caloric intake should be fat. On the other hand, Robert Atkins recommends the elimination of all carbohydrate with no restriction on fat. It has been estimated that the average Atkins dieter consumes 61% of Calories from fat.
From a record of food eaten in one day, you are to compute the percent Calories from fat. The record consists of one line of input per food item, giving the quantity of fat, protein, sugar, starch and alcohol in each. Each quantity is an integer followed by a unit, which will be one of: g (grams), C (Calories), or % (percent Calories). Percentages will be between 0 and 99. At least one of the ingredients will be given as a non-zero quantity of grams or Calories (not percent Calories).

Input

Input will consist of several test cases. Each test case will have one or more lines as described above. Each test case will be terminated by a line containing '-'. An additional line containing '-' will follow the last test case.

Output

For each test case, print percent Calories from fat, rounded to the nearest integer.

Sample Input

3g 10g 10% 0g 0g

55% 100C 0% 0g 30g

25g 0g 0g 0g 0g

1g 15% 20% 30% 1C

Sample Output

53%
100%
32%

题意:每天人都要摄入各种食物,然后每种食物,可能含有脂肪,蛋白质,盐,淀粉,酒精这些东西的一种或者几种。然后求出每日从这些食物中从脂肪中摄取的卡路里的总数占每天摄入的所有卡路里总数的百分比。注意要四舍五入输出。 分析:没啥算法,思路就是求出所有的的脂肪卡路里和所有的卡路里,然后求就行。 注意的东西:如何控制输入输出的格式,如何控制四舍五入   控制四舍五入的几种方法: 1.#include #
