A mutex is a synchronization primitive that ensures only one thread can access a resource at a time.
Create a mutex object using the appropriate library or language-specific function.
Lock the mutex before accessing the shared resource to prevent other threads from accessing it.
Unlock the mutex after finishing the operation on the shared resource to allow other threads to access it.
Example: pthread_mutex_t mutex; pthread...
Identify memory leak in code
Check for any dynamically allocated memory that is not being freed
Look for any infinite loops or recursive functions that consume memory
Use memory profiling tools like Valgrind to detect leaks
Check for any global variables that are not properly managed
I was interviewed before Mar 2021.
To check if a number is a power of 2, we can use bitwise operations.
A power of 2 has only one bit set to 1, so we can use the bitwise AND operator to check if the number is a power of 2.
If n is a power of 2, then n & (n-1) will be 0.
For example, 8 (1000 in binary) is a power of 2, and 8 & 7 (0111 in binary) is 0.
Sort a stack without using another data structure
Use recursion to pop the top element and insert it at the bottom of the remaining stack
Repeat until the stack is sorted in ascending order
Time complexity: O(n^2), space complexity: O(n) due to recursion
Check if array has continuous increasing and decreasing values
Loop through the array and check if each element is greater than the previous one
Once you find the maximum element, check if the remaining elements are in decreasing order
If yes, return true else false
Design a cricinfo (LLD)
Identify the entities: players, teams, matches, scorecards, tournaments, etc.
Define the relationships between entities
Create a database schema to store the data
Implement APIs to fetch and update data
Design a UI to display the information
Consider scalability and performance
Ensure data security and privacy

IPC mechanism in Windows allows communication between processes through shared memory, message passing, and synchronization.
IPC mechanisms in Windows include named pipes, mailslots, shared memory, and sockets.
Named pipes allow communication between processes on the same machine or over a network.
Mailslots are used for one-way interprocess communication.
Shared memory allows processes to share data by mapping a region of...
Multi-threading in Windows allows multiple threads to run concurrently within a single process.
Windows provides APIs like CreateThread and CreateProcess to create and manage threads.
Threads share the same memory space within a process, allowing for efficient communication and resource sharing.
Windows supports both user-mode and kernel-mode threads, with user-mode threads being more lightweight.
Synchronization mechanism...
Memory mapping in Windows allows files to be mapped directly into memory for faster access and manipulation.
Memory mapping allows files to be accessed as if they were in memory
File mapping can be used for sharing data between processes
Improves performance by reducing disk I/O operations
Examples: CreateFileMapping, MapViewOfFile, UnmapViewOfFile
Critical section in Windows is a synchronization mechanism used to protect shared resources from concurrent access.
Critical sections are used to ensure mutual exclusion between threads accessing shared resources.
They are implemented using the Windows API functions InitializeCriticalSection, EnterCriticalSection, and LeaveCriticalSection.
Critical sections are more efficient than mutexes for synchronization within a sing...
