@5:45 She actually means that time complexity to "get" an element by index is O(1). While time complexity to "search" an element in an ArrayList is O(n) which is same as of linked list since we iterate over the entire list to search for a particular element.

06:07 Linked list is a data structure that consists of nodes linked together. 12:14 Linked list is a data structure that links different data together 18:21 Linked list is a data structure in which each element is connected to the next element through a chain of pointers. 24:28 Insertion and deletion operations are key in linked lists. 30:35 Traversal and manipulation of linked lists 36:42 Two key operations in Linked List are add and delete 42:49 Linked list operations in Java 48:50 Link list in Java can be used to add, remove, and traverse elements.

Very good idea of starting linked list before binary search. Because if you study binary search first then during practising on leetcode or any platform Usually public submitted their answers in advanced form which we are unable to understand.

@7:40 time complexity to insert "at the start of linked list" is O(1) while the time complexity to insert at end of the list or in the middle of list is O(n) because first we have to traverse the list to reach that node after which we want to insert new node.
