<ul><li>Given a 0-indexed 2D integer array 'questions' representing an exam where each question has points and brainpower constraints.</li><li>The task is to maximize points by solving questions considering brainpower limitations.</li><li>Dynamic Programming is suggested to decide the most optimal option for each question.</li><li>Solution involves DP array to track maximum points starting from each question.</li><li>For each question, two choices exist: solve with constraints or skip to the next.</li><li>Reverse iteration helps in considering each question's impact on future questions.</li><li>The algorithm efficiently determines the maximum points earned from solving exam questions.</li><li>Initialization of DP array and iterating from last question aids in optimal point calculation.</li><li>The approach computes the solution in O(n) time and space complexity for large input sizes.</li><li>Dynamic Programming is a powerful technique for optimizing decision-making processes in various scenarios.</li></ul>
