I appeared for an interview before Mar 2024, where I was asked the following questions.
To find the middle node of a linked list, use the two-pointer technique: one moves fast, the other slow.
Use two pointers: 'slow' and 'fast'.
Initialize both pointers at the head of the list.
Move 'slow' by one step and 'fast' by two steps in each iteration.
When 'fast' reaches the end, 'slow' will be at the middle.
Example: For the list 1 -> 2 -> 3 -> 4 -> 5, 'slow' will point to 3.
The height of a binary tree is the length of the longest path from the root to a leaf node.
Height is defined as the number of edges in the longest path from the root to a leaf.
For a tree with only one node (the root), the height is 0.
Example: In a tree with root and two children, the height is 1.
A complete binary tree of height h has 2^(h+1) - 1 nodes.
The height can be calculated recursively: height(node) = 1 + max(hei...
