Ans. 
I knew that this has to be done in O(n logn ) or less time complexity so I approached in this way :
 
Intuition
From root, say the target node is at depth 3 in the left branch. It means that any nodes that are distance K - 3 in the right branch should be added to the answer.
 
Algorithm
Traverse every node with a depth first search dfs. We'll add all nodes x to the answer such that node is the node on the path from

Q2. Computer System Architecture
What is TLB? Why is it used? What are huge pages and their advantages? Which is accessed first TLB or cache? Can we access TLB and cache in parallel?
Ans. 
My Answer :
Huge pages are larger in size and require less number of TLB entries for the same amount of memory. This leads to larger virtual address space being cached and hence better performance. Out of TLB and cache, TLB is accessed first because virtual memory address must first be translated to the physical memory address and then this address is used to access data from the cache. TLB and cache can be accessed in ...read more

Q3. System Architecture
How are system calls made at assembly level? How are IO operations like cout translated at low level?
Ans. 
System calls are made through software interrupts (int 0x40 in x86 architecture) and system call number and system call parameters are given as parameters to the software interrupt handler. IO operations like cout internally make system calls (write system call in this case to stdout) to a file descriptor.

Tips : Know the basic working of your commands .
Revise your Core Subjects before appearing in Interviews.
