Healthy Living Calories

You are tracking the calories consumed by a group of individuals over a week. You want to know the total calories consumed up to certain days. Write a program that reads the total calorie intake for 7 days and returns the cumulative calorie counts for the specified days. For example, given the input: 7 500 600 300 400 700 300 800 3 1 3 5 You should output: 500 1400 2400 This is because the cumulative calories for day 1, day 3, and day 5 are 500, 1400, and 2400 respectively.
