Which of the following statements are correct regarding the time complexity of getting the index of an item in a list? In an array-based implementation of lists, the worst-case time complexity of getting the index of an item in a list is O(n). In a linked list implementation, the worst-case time complexity of getting the index of an item in a list is O(1). Which of the following statements are correct regarding the time complexity of removing an item from a list? In an array-based implementation of lists, the worst-case time complexity of removing an item given the index of the item is O(n). In a linked list implementation, the worst-case time complexity of removing an item given the index of the item is O(n).       Which of the following statements are correct about adding an element to a list implemented using arrays with no maximum limit for the number of elements and array growing? Adding an element may require copying elements to a new array in some cases. The worst-case time complexity of adding an element is O(1)
