WebbWoDoSc was nice enough to draw a diagram of the elevations and trapped water. The water can only be trapped between two higher elevations. What I did was run the code and output the results so you can see how the trapped water is calculated. The code starts at both ends of the "mountain" range. Whichever end is lower is moved closer to the center. Webb2 okt. 2024 · Photo by Cristi Goia on Unsplash. For my last technical interview, I was asked about how to trap rainwater. (Not really 🤪).

WebbExample 1: Input: heightMap = [ [1,4,3,1,3,2], [3,2,1,3,2,4], [2,3,3,2,3,1]] Output: 4 Explanation: After the rain, water is trapped between the blocks. We have two small ponds 1 and 3 units trapped. The total volume of water trapped is 4. Example 2: Input: heightMap = [ [3,3,3,3,3], [3,2,2,2,3], [3,2,1,2,3], [3,2,2,2,3], [3,3,3,3,3]] Output: 10 WebbIt is raining in Geek City.
