Solution: Diet Plan Performance

Explore how to apply the sliding window method to track a dieter's performance by calculating calorie sums over sequences of consecutive days. This lesson helps you understand updating sums efficiently to evaluate and score dietary performance using optimal time and space complexity.

We'll cover the following...

Statement

A dieter consumes calories[i] calories on the i-th day.

Given an integer k, the dieter reviews their calorie intake over every sequence of k consecutive days (from calories[i] to calories[i+k-1] for all 0 <= i <= n-k). For each sequence, they calculate T, the total calories consumed over those k days:

  • If T is less than lower, the dieter ...
