Merging N sorted log files involves using a min-heap to efficiently combine entries by timestamp.
Use a min-heap (priority queue) to keep track of the smallest timestamp from each file.
Initialize the heap with the first entry from each log file.
Extract the smallest entry from the heap, and add it to the merged output.
If the extracted entry has a next entry in its original file, push that next entry into the heap.

TCP is connection-oriented and reliable, while UDP is connectionless and faster but less reliable.
TCP (Transmission Control Protocol) ensures reliable data transmission with error checking and correction.
UDP (User Datagram Protocol) is faster and suitable for applications where speed is critical, like video streaming.
TCP establishes a connection before data transfer, while UDP sends data without establishing a con...
Common in 2 threads: share same memory space, variables, code, and resources. Difference: have separate execution paths and stack.
Common: share same memory space, variables, code, and resources
Difference: have separate execution paths and stack
Example: Two threads in a process sharing access to a global variable
Check if 4 selected boxes in a 2-D array of chars are continuous in the 3x3 sub array surrounding each box.
Iterate through the selected boxes and check if they are within the 3x3 sub array of each box.
Consider edge cases where the selected boxes are at the boundaries of the array.
Example: If the selected boxes are (1,1), (1,2), (2,1), (2,2), they form a continuous 2x2 sub array.

Sort a large int array in the range 1-10.
Use counting sort algorithm for efficient sorting.
Create a count array to store the frequency of each number.
Iterate through the count array to reconstruct the sorted array.
Given multiple rectangles on a screen, find the smallest rectangle enclosing a user-clicked point.
Iterate through each rectangle and check if the clicked point lies within its boundaries
Keep track of the smallest enclosing rectangle found so far
Return the smallest enclosing rectangle
Given a Y-linked list, find the node at the intersection point.
Traverse both branches of the Y-linked list and compare nodes.
Use a hash table to store visited nodes and check for intersection.
If one branch is longer, traverse it until it matches the length of the other branch.
Remove duplicate characters from a string while preserving order.
Create an empty string to hold the result.
Iterate through each character in the input string.
If the character is not already in the result string, add it.
Return the result string.
Traverse a binary tree in spiral order, alternating between left-to-right and right-to-left at each level.
Use two stacks: one for the current level and one for the next level.
Start with the root node in the first stack.
While there are nodes in the current stack, pop nodes and add their children to the next stack in the opposite order.
Switch stacks after each level to alternate the traversal direction.
Example: For ...
Find the lowest common ancestor (LCA) of two nodes in a binary search tree (BST) efficiently.
In a BST, for any node, left children are smaller and right children are larger.
To find LCA of nodes p and q, start from the root.
If both p and q are smaller than the root, LCA lies in the left subtree.
If both p and q are larger than the root, LCA lies in the right subtree.
If one is on the left and the other is on the righ...
