Implement a stack that supports finding the minimum element in constant time.
Use two stacks - one to store the actual elements and another to store the minimum values at each level.
When pushing an element, compare it with the current minimum and push the smaller value onto the minimum stack.
When popping an element, also pop from the minimum stack if the popped element is the current minimum.

LCA (Lowest Common Ancestor) of given nodes in a tree is the node that is the lowest common ancestor of the given nodes.
Traverse the tree to find the paths from the root to each of the given nodes.
Compare the paths to find the last common node, which is the LCA.
If one of the given nodes is the ancestor of the other, return the ancestor node as the LCA.
