LeetCode interview question 17.21 water volume of histogram
Title Link: LeetCode interview question 17.21 water volume of histogram
Main idea of the title:
Solution:
dynamic programming
For the subscript \ (I \), the maximum height that the water can reach is equal to the minimum value of the maximum height on both sides of the subscript \ (I \), so you can use dynamic programming to deduce the maximum ...
