Solution: Diet Plan Performance

Understand how to apply the sliding window technique to solve the Diet Plan Performance problem. Learn to efficiently calculate calorie sums for consecutive days and adjust performance points based on given thresholds, gaining insights into time and space optimization.

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 ...
