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
