Jack is given an array arr[] of 11 elements. The elements are 27, 33, 61, 2, 3, 28, 59, 15, 19, 13, 7. He is instructed to rearrange the elements in non-decreasing order. Which of the following statements given below is incorrect?

Suppose you have an array arr[] = { 3,2,9,10,54,21). You want to make min heap using the elements of this array. What will be the left child of the root? In Min Heap, child nodes are greater than parent nodes and this property is recursively true.

• 2

• only 3

• only 9

• either 3 or 9

Suppose you are given a stack and 5 elements (1,2,3,4,5). You have inserted these elements into the stack in the given order. 1->2->3->4->5. Now you have reversed the stack. After reversing the stack which will be the top element of the stack?

• 3

• 5

• 1

• 4

What will be the value of the array after performing below operations? Consider the following array of size 4. arr(1,4,3,5). Reverse the array. Sort in Increasing order. Reverse the array.

• (1,4,3,5)

• (1,3,4,5)

• (5,4,3,1)

• (5,3,4,1)

Consider a singly circular linked list, how many number of address fields are present in a node?

• 1

• 2
