The question asks to find the total amount of rainwater that can be trapped in the given elevation map.

• Iterate through the array and find the maximum height on the left and right of each bar.

• Calculate the amount of water that can be trapped at each bar by subtracting its height from the minimum of the maximum heights on the left and right.

• Sum up the amount of water trapped at each bar to get the total amount of rainwater trapped.

The task is to find the minimum number of edges that need to be reversed in a directed graph to find the path from a start node to an end node.

• The problem can be solved using graph traversal algorithms like Breadth First Search (BFS) or Depth First Search (DFS).

• Start by creating an adjacency list representation of the directed graph.

• Perform a BFS or DFS from the start node to the end node, keeping track of the number of edges reversed.

• Return the minimum number of edges revers...read more

The rain water problem involves calculating the amount of rainwater that can be trapped between buildings or structures.

• Calculate the maximum height of water that can be trapped at each position

• Subtract the height of the building at each position to get the water level

• Sum up the water levels at each position to get the total amount of trapped rainwater

The task is to find all distinct triplets in an array that add up to a given sum.

• Iterate through the array and fix the first element of the triplet.

• Use two pointers approach to find the other two elements that sum up to the remaining target.

• Handle duplicates by skipping duplicate elements while iterating.

• Return the list of valid triplets.

Merge two sorted linked lists into a single sorted linked list without using additional space.

• Create a dummy node to start the merged list

• Compare the values of the two linked lists and add the smaller value to the merged list

• Move the pointer of the merged list and the pointer of the smaller value list

• Continue this process until one of the lists is fully traversed

• Append the remaining elements of the other list to the merged list

To cut a rod in such a way that each part is obtained every day and the whole rod is obtained in a week.

• Cut the rod into 7 equal parts.

• Each day, use one part of the rod.

• By the end of the week, all parts will be used and the whole rod will be obtained.
