Dam Segment Capacity
Dam Segment Capacity
Easy
Two Pointers
In "Dam Segment Capacity", each number is the height of a wall with width 1.
Compute how many total units of rainwater are trapped after rainfall.
Example 1
Input:
height = [0,2,1,3,0,1,2]Output:
4For input height = [0,2,1,3,0,1,2], summing trapped water over each position gives 4. Therefore, return 4.
Example 2
Input:
height = [4,1,0,2,3,0,2]Output:
8For input height = [4,1,0,2,3,0,2], summing trapped water over each position gives 8. Therefore, return 8.
Constraints
1 <= height.length <= 2 * 1040 <= height[i] <= 105
