[algorithm] [difficulty] – water volume of histogram – dynamic programming
17.21. Water volume of histogram Difficulty: [difficulty] Given a histogram (also known as histogram), suppose someone pours water continuously from it, how much water can the histogram store in the end? The width of the histogram is 1. The above is the histogram represented by the array [0,1,0,2,1,0,1,3,2,1,2,1]. In this case, 6 units of water […]
