Solution: Diet Plan Performance

Understand how to use the sliding window method to analyze sequences of consecutive days' calorie intake. This lesson teaches you to update calorie sums efficiently and calculate points based on comparisons to lower and upper calorie thresholds, helping you implement an O(n) time and O(1) space complexity solution for the diet plan problem.

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 ...
