Grokking the Coding Interview Patterns in C#

Solution: Diet Plan Performance

Understand how to implement the sliding window approach to solve the Diet Plan Performance problem by calculating calorie sums over consecutive days. This lesson helps you track performance points efficiently and optimize time and space complexity for coding interviews.

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 ...
