Program to find lowest common ancestor of two nodes in a binary tree with unique values.
Start from the root and traverse the tree to find the paths from root to the two nodes.
Compare the paths to find the lowest common ancestor node.
Use recursion to traverse the tree efficiently.
Handle edge cases like if one of the nodes is the ancestor of the other.
Program to find longest consecutive sequence and length of longest path in a binary tree.
Traverse the binary tree using depth-first search (DFS)
Keep track of the current consecutive sequence length and the longest consecutive sequence found so far
Update the length of the longest path as you traverse the tree
Return the next lexicographically greater permutation of a given sequence or return it in ascending order if not possible.
Use the concept of lexicographic ordering to find the next permutation.
If the sequence is already in descending order, return it in ascending order.
Examples: ['a', 'b', 'c'] -> ['a', 'c', 'b'], ['3', '2', '1'] -> ['1', '2', '3']
Use sliding window technique to find minimum window in s containing all characters of t.
Use two pointers to create a window in s
Move the right pointer to expand the window until all characters of t are found
Move the left pointer to shrink the window while maintaining all characters of t
Update minimum window size as you iterate through s
Use a max heap to keep track of the K largest elements in a continuous stream of integers.
Create a max heap of size K to store the K largest elements.
For each new element in the stream, compare it with the root of the max heap. If it is larger, replace the root with the new element and heapify.
At any point, the root of the max heap will be the Kth largest element in the stream.
