- Which of the following data structures store values in contiguous memory? Check all that apply . Vector Linked List Dynamic Array Map ArrayWhich of the following code segments will use vectorisation to reduce the time taken to calculate the sum of two NumPy arrays: A and B? (Select ALL that apply) 1. ) C = np.empty(A.size) for index in range(A.size): C[index] = A[index] + B[index] 2.) A.tolist()+B.tolist() 3.) np.sum([A, B]) 4.) A+BWhich of the following statements is true about accessing array elements in C++? a. Array elements can only be accessed sequentially from the first element. b. Array elements can be accessed randomly using their indices. c. Array elements are not easily accessible. d. Array elements can only be accessed using a loop. e. Array elements cannot be accessed directly.
- Create two dynamic arrays A and B with random numbers.a) Merge B in array A calling a function by reference.b) Delete the composite numbers from the merged array A calling a function bypointer. You have to use only two Arrays A and B throughout the code. Be carefulabout memory leakage.Which of the following are true about arrays? Arrays are reference types. Array indexing is bounds‐checked. Arrays sometimes can be created without using new. The entire contents of an array can be copied via =.An_array and a number kFind the max elements of each of its sub-arrays of length k. Keep indexes of good candidates in deque d.The indexes in d are from the current window, they're increasing,and their corresponding nums are decreasing.Then the first deque element is the index of the largest window value. For each index i: 1. Pop (from the end) indexes of smaller elements (they'll be useless).2. Append the current index.3. Pop (from the front) the index i - k, if it's still in the deque (it falls out of the window).4. If our window has reached size k, append the current window maximum to the output..
