📝Code Description:
This Java code solves the “Minimum Height Shelves” problem using Dynamic Programming. Each book has a width and height, and the goal is to arrange the books in order onto shelves such that the total height of all shelves is minimized, while ensuring the total width of books on each shelf does not exceed shelfWidth.
The algorithm uses a 1D DP array where dp[i] represents the minimum height needed to place the first i books. For each book, it tries to group it with previous books on the same shelf as long as the width constraint is satisfied, keeping track of the tallest book on that shelf. It calculates the optimal combination to update the minimum total height.
This approach ensures an optimal solution with O(n²) complexity by exploring all valid ways of placing books on shelves.
