Logic Fruit Technologies System Administrator Interview Questions and Answers

To delete a node in a single linked list, update the previous node's next pointer to skip over the node to be deleted.

• Traverse the linked list to find the node to be deleted

• Update the previous node's next pointer to skip over the node to be deleted

• Free the memory allocated to the node to be deleted

Use two pointers to iterate through the list and remove duplicates by updating next pointers

• Initialize two pointers, current and next, to iterate through the list

• Compare current and next node values, if equal, update next pointer to skip duplicate node

• Repeat until end of list is reached

Volatile and extern are keywords in C for memory management. Local and external linkages determine scope. SW and HW interrupts handle events. Different scheduling algorithms manage task priorities.

• Volatile keyword is used to indicate that a variable may be changed unexpectedly, typically by hardware. Example: volatile int x;

• Extern keyword is used to declare a variable that is defined in another file. Example: extern in...read more
