Round 1: Technical Interview

Questions:

1. C/C++ pointers questions.
2. Implement Reverse a LinkedList from start point to end in a linkedlist.
   • Example (i):
     • List = [10, 20, 30, 40, 50, 60], start = 2, end = 5
     • Output = [10, 50, 40, 30, 20, 60]
   • Example (ii):
     • List = [10, 20, 30, 40, 50, 60], start = 1, end = 5
     • Output = [50, 40, 30, 20, 10, 60]
   • Example (iii):
     • List = [10, 20, 30, 40, 50, 60], start = 1, end = 6
     • Output = [60, 50, 40, 30, 20, 10]
   • Write a working code from the start and execute it against all the cases.
3. What is stack overflow? Will while(1) {} cause stack overflow?
4. Basic bits manipulation questions on how to extract IP address from a uint32 bit integer value (0-7, 8-15, 16-23, 24-31 .. every 8 bits representing the IP address bits).
