Addison Interview Questions, Process, and Tips

Find two numbers in an array that add up to a specified target sum.

• Use a hash map to store numbers and their indices for quick lookup.

• Iterate through the array and check if target - current number exists in the map.

• Example: For array [2, 7, 11, 15] and target 9, return (2, 7).

• Time complexity is O(n) due to single pass through the array.

Sort a linked list using various algorithms like Merge Sort or Quick Sort for efficient performance.

• Use Merge Sort for linked lists as it has O(n log n) time complexity and is stable.

• Iterate through the list and split it into two halves recursively until base cases are reached.

• Merge the sorted halves back together by comparing node values.

• Example: For the list 4 -> 2 -> 1 -> 3, the sorted output will be 1 ->
