denotes the elevation of the ith
bar. Your task is to determine th...
Calculate the total amount of rainwater that can be trapped between given elevations in an array.
Iterate through the array and calculate the maximum height on the left and right of each bar.
Calculate the amount of water that can be trapped at each bar by taking the minimum of the maximum heights on the left and right.
Sum up the trapped water at each bar to get the total trapped water for the entire array.

DSA - arrays, hashing, stack, 2hrs , google meet
Calculate the maximum amount of rainwater that can be trapped between the bars of varying heights.
Use two pointers to traverse the array from both ends.
Maintain two variables to track the maximum height from left and right.
Calculate trapped water at each position based on the minimum of the two maximum heights.
Example: For heights [0,1,0,2,1,0,1,3,2,1,2,1], the result is 6.
