Count the number of islands in a 2D grid of '1's (land) and '0's (water).
Use Depth-First Search (DFS) or Breadth-First Search (BFS) to explore each island.
Iterate through each cell in the grid; if a '1' is found, increment the island count and explore its neighbors.
Mark visited land cells as '0' to avoid counting them again.
Example: For grid [['1','1','0'], ['0','0','1'], ['1','0','1']], the output is 4 islands.
Trees are data structures used to store hierarchical data. They are commonly used in algorithms and problem-solving.
Trees have a root node and branches that connect to other nodes.
Common tree traversal methods include in-order, pre-order, and post-order.
Examples of tree-based problems include finding the lowest common ancestor, balancing a binary search tree, and implementing a trie data structure.

Adapt Fitbit's marketing strategy to cater to the preferences and needs of consumers in different geographies

Efficiently retrieve the minimum value from a stream of numbers using a query-based approach.
Use a priority queue (min-heap) to keep track of the minimum values as they come in.
For each new number, compare it with the current minimum and update if necessary.
Example: Stream = [5, 3, 8, 1]; Min = 1 after processing all.
Consider edge cases like empty streams or negative numbers.
Calculate the minimum number of train platforms required based on given arrival and departure times.
Sort the arrival and departure times.
Use two pointers to traverse the sorted lists.
Count the number of trains at the station at any time.
Update the maximum count of platforms needed.
Example: For arrivals [10:00, 10:15, 10:30] and departures [10:10, 10:20, 10:40], 2 platforms are needed.
Count the number of islands in a tree structure
Traverse the tree and identify connected components
Use depth-first search or breadth-first search to explore the tree
Keep track of visited nodes to avoid revisiting them
An island is a group of connected nodes with no connections to other nodes
Count the number of distinct islands in a tree with 0's and 1's where joined 1's form an island.
Traverse the tree and identify connected components of 1's to form islands.
Use a set to store the unique shapes of islands to avoid counting duplicates.
Consider different shapes of islands like horizontal, vertical, diagonal, etc.
Example: [['1', '0', '1'], ['1', '1', '0']] has 2 distinct islands.
