Round 2 - Technical 

(5 Questions)

  • Q1. Volatile usage w.r.t to gpio initialization, how volatile can help in overwriting compiler optimization.
  • Ans. 

    Volatile keyword prevents compiler optimization by telling the compiler that the variable's value can change unexpectedly.

    • Volatile keyword is used to indicate that a variable may be changed unexpectedly, such as in the case of hardware registers.

    • When initializing GPIO pins, using volatile keyword ensures that the compiler does not optimize away the initialization code.

    • Without volatile keyword, the compiler may optimize...

  • Q1. Coding question on dll and bits
  • Q2. Detect and remove loop in ll
  • Ans. 

    To detect and remove a loop in a linked list, we can use Floyd's Cycle Detection Algorithm.

    • Use two pointers, slow and fast, to traverse the linked list

    • If there is a loop, the fast pointer will eventually meet the slow pointer

    • Once the loop is detected, reset one of the pointers to the head and move both pointers at the same pace until they meet again to find the start of the loop
