ANSWER IN ONE NUMBER/WORD/SENTENCE 1.A sorted array contains 300,000 elements. The maximum number of operations needed by binary search to check if an element is present in the array would be 2.The correct statement indicating the recurrence relation for mergesort is Blank 1 302: T(n) = T(n/2) + n 303: T(n) = 2T(n/2) + n/2 304: T(n) = 2T(n/2) + n 306: T(n) = T(n – 1) + 3n 3.Put the most appropriate statement number here 171: Insertion at the end of an array structure takes O(1) time and insertion at the end of a linked list takes O(n) time. 172: Searching the largest element in a random array takes O(log n) 173: Deletion of first element takes O(1) for an array and O(1) for a linked list 174: Searching for mid element takes O(log n) both for a sorted array and a sorted linked list 4.An array contains following elements: 20 42 8 66 12 39 11 26 33 The mergesort method we discussed in the class calls a merge function.
