Which one of the following is NOT a valid identity?

Option A. (x ⨁ y) ⨁ z = x ⨁ (y ⨁ z)
Option B. (x + y) ⨁ z = x ⨁ (y + z)
Option C. x ⨁ y = x + y, if xy = 0
Option D. x ⨁ y = (xy + x′y′)′
True Answer B

Explanation :

 (a) x  y = (xy + x′y ′)′

= (xy )′

= x  y, it is valid.

(b) 

= Σm(1, 2, 4, 6)

= Σm(1, 2, 3, 4)

(x + y)  z ≠ x  (y + z)

So option (b) is invalid.

(c) (x  y)  z = x  (y  z)

Associativity is true on Ex-OR operator so it valid.

(d) 

= (x + y), so it is valid.

Which one of the following is NOT a valid identity?

In a binary tree with n nodes, every node has an odd number of descendants. Every node is considered to be its own descendant. What is the number of nodes in the tree that have exactly one child?

Option A. 0
Option B. 1
Option C. (n - 1) /2
Option D. n – 1
True Answer A

Explanation :

 Given that a node has odd number of descendants possible only when it is fully binary tree like.

So in fully binary tree, every node has two child or zero child (zero child when there is one node exactly)
So the number of nodes in tree that type having exactly one child is zero.

In a binary tree with n nodes, every node has an odd number of descendants. Every node is considered to be its own descendant. What is the number of nodes in the tree that have exactly one child?

Which one of the following is the tightest upper bound that represents the number of swaps required to sort n numbers using selection sort?

Option A. O(log n)
Option B. O(n)
Option C. O(n log n)
Option D. O(n2)
True Answer B

Explanation :

 Given: n number
To find: Tighest upper bound on number of swaps required to sort n numbers using selection sort.
Analysis: In selection sort, in the unsorted part of the array, we find the minimum element and swap it with the value placed at the index where the unsorted array starts.
Hence, for each element to put it in its sorted position, we will do some swaps. In each iteration, when we find the minimum and place it in its sorted position, we do only one swap.
There are n such iterations, since maximum number of positions to sort is n.
Hence, there are n. 0(1) swaps
swaps.
 The solution is (b)

Which one of the following is the tightest upper bound that represents the number of swaps required to sort n numbers using selection sort?

What will be the output of the following Python expression if the value of x is 34?

print(“%f”%x)

Option A. 34.00
Option B. 34.0000
Option C. 34.000000
Option D. 34.00000000
True Answer C

Explanation :
The expression shown above normally returns the value with 6 decimal points if it is not specified with any number. Hence the output of this expression will be: 34.000000 (6 decimal points).
