Solution: Diet Plan Performance

Explore how to use the sliding window technique to efficiently calculate calorie sums for consecutive days. Learn to assess diet performance by assigning points based on calorie thresholds, mastering an O(n) time complexity solution that updates scores by sliding through the data set.

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 ...
