Which data structure allows constant time (O(1)) access to any element by index: array or linked list?
Given this scenario: You need to frequently insert elements at the beginning of a collection. Which data structure is more efficient?
Which data structure stores all its elements in contiguous memory locations?
If you need a collection that can easily grow or shrink in size, which structure is typically better: array or linked list?
Suppose you want to access the 10th item in a 1000-element list. Which data structure provides faster access?
Consider inserting a value in the middle of a large collection. Which structure generally offers better performance for this operation?
To delete an element by value (not by index), which data structure avoids unnecessary data movement?
Given the code 'int arr[5] = {1, 2, 3, 4, 5};', what type of data structure is 'arr'?
Which data structure generally requires extra memory per element to store pointers or references?
You have a collection of fixed size and need fast access to elements by index—what's the better choice?
