⏱ O(n)

2️⃣2️⃣3️⃣ Find the Intersection Point of Two Linked Lists
👉 Traverse both lists, switching heads when reaching the end, so paths align.

def get_intersection(headA, headB):
    a, b = headA, headB

2️⃣2️⃣8️⃣ Find the Lowest Common Ancestor in a BST
👉 Traverse down; split point where paths diverge is the LCA.

def lowest_common_ancestor(root, p, q):
    while root:
        if p < root.data and q < root.data:
            root = root.left
        elif p > root.data and q > root.data:
            root = root.right
        else:
            return root.data

2️⃣2️⃣9️⃣ Check if Two Binary Trees are Identical
👉 Compare values and recursively check both subtrees.

def is_identical(t1, t2):
    if not t1 and not t2:
        return True
    if not t1 or not t2:
        return False
    return (t1.data == t2.data and
            is_identical(t1.left, t2.left) and
            is_identical(t1.right, t2.right))

2️⃣3️⃣0️⃣ Find the Diameter of a Binary Tree
👉 The longest path between any two nodes — may or may not pass through root.

def diameter(root):
    result = [0]
    def depth(node):
        if not node:
            return 0
        left = depth(node.left)
        right = depth(node.right)
        result[0] = max(result[0], left + right)
        return 1 + max(left, right)
    depth(root)
    return result[0]
