- Q1. Reverse a linked list
- Ans.
Reverse a linked list by changing the next pointers of each node
Initialize three pointers: prev = null, current = head, next = null
Iterate through the linked list, updating next to current's next, current's next to prev, and moving prev and current pointers forward
Return the new head, which is the last node visited
- Q2. Find a bit is set
- Ans.
To find if a bit is set, use bitwise AND operator with the bit position
Use bitwise AND operator (&) with the bit position to check if it is set
If the result is greater than 0, then the bit is set
Example: Check if 3rd bit is set in binary number 1010 - (1010 & 0100) = 0100 (4), so 3rd bit is set
- Q3. Create a thread in process
- Ans.
Creating a thread in a process involves allocating resources for a new thread to run concurrently with other threads.
Use threading libraries like pthreads in C or java.util.concurrent in Java
Create a new thread object and pass a function or method to be executed by the thread
