Finding lowest common ancestor of two nodes in binary tree
Traverse the tree from root to both nodes and store the paths in separate arrays
Compare the paths to find the last common node
Return the last common node as the lowest common ancestor
Use recursion to traverse the tree efficiently
To find the merging point of two linked lists
Traverse both linked lists and find their lengths
Move the pointer of the longer list by the difference in lengths
Traverse both lists simultaneously until they meet at the merging point
Reverse a linked list iteratively
Create three pointers: prev, curr, and next
Initialize prev to null and curr to head
Loop through the list and set next to curr's next node
Set curr's next node to prev
Move prev and curr one step forward
Return prev as the new head
The number of rectangles in an MxN matrix can be calculated using a formula.
The formula is (M * (M + 1) * N * (N + 1)) / 4
The matrix can be divided into smaller sub-matrices to count the rectangles
The number of rectangles can also be calculated by counting all possible pairs of rows and columns
The number is 7744.
The number must end in 00 or 44.
The square root of the number must be a whole number.
The only possible number is 7744.

Inner join returns only the matching rows between two tables, while outer join returns all rows from one table and matching rows from the other.
Inner join combines rows from two tables based on a matching column.
Outer join returns all rows from one table and matching rows from the other.
Left outer join returns all rows from the left table and matching rows from the right table.
Right outer join returns all rows from the...
To find the length of non-looped linked list, we need to traverse the list and count the number of nodes.
Traverse the linked list using a pointer and count the number of nodes until the end of the list is reached.
If a loop is encountered, break out of the loop and continue counting until the end of the list.
Return the count as the length of the non-looped linked list.
