Describe an advanced data structure : Array Problems Involving Modulos

The video tutorial covers the modulo operation, explaining its properties and how it applies to arrays. It introduces a problem of finding the minimum length subarray with a sum mod K equal to zero, demonstrating an efficient implementation using prefix sums and dictionaries. A new problem is introduced, involving removing elements from an array to achieve a sum mod 3 equal to zero.
