about removing an element from a vector data structure? (a) It is computationally cheaper to remove an element at a lower index than it is to Q1: What is true remove an element at a higher index (b) Removing the element at highest index is always an O(1) operation. (c) The vector data structure is designed to be a container of elements; it does not support element removal. (d) Removing the highest index element involves shifting mySize-1 many elements one position to the right. 22: What is the purpose of the T objects: ' data member in the implementation of emplate Vector ....? (a) An indication that the elements to be stored in the vector are going to be pointers to type T. (b) This is a mistake and should be corrected to 'T objects;" (c) It is a pointer to the first element on an array of type T. (d) It clears the buffer that stores the vector elements that are no longer wanted
