Bit Manipulation Basics AND OR XOR NOT Left Right Shift in DSA Python - Interactive Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to perform bitwise AND of two numbers.

DSA Python

result = a [1] b

Drag options to blanks, or click blank then click option'

A^

B|

C&

D~

Attempts:

3 left

💡 Hint

Common Mistakes

Using | instead of & will perform OR operation.

Using ^ will perform XOR, not AND.

The bitwise AND operator & compares each bit of two numbers and returns 1 only if both bits are 1.

2fill in blank

medium

Complete the code to perform bitwise OR of two numbers.

DSA Python

result = x [1] y

Drag options to blanks, or click blank then click option'

A^

B|

C&

D~

Attempts:

3 left

💡 Hint

Common Mistakes

Using & instead of | will perform AND operation.

Using ^ will perform XOR, not OR.

The bitwise OR operator | compares each bit of two numbers and returns 1 if at least one bit is 1.

3fill in blank

hard

Fix the error in the code to perform bitwise XOR of two numbers.

DSA Python

result = num1 [1] num2

Drag options to blanks, or click blank then click option'

A&

B|

C~

D^

Attempts:

3 left

💡 Hint

Common Mistakes

Using & or | instead of ^ will give wrong results.

Using ~ is bitwise NOT, not XOR.

The bitwise XOR operator ^ returns 1 only if the bits are different.

4fill in blank

hard

Fill both blanks to perform left shift and right shift operations.

DSA Python

left_shift = val [1] 2
right_shift = val [2] 2

Drag options to blanks, or click blank then click option'

A<<

B>>

C&

D|

Attempts:

3 left

💡 Hint

Common Mistakes

Using & or | instead of shift operators.

Mixing up left and right shift operators.

Left shift << moves bits to the left, multiplying by powers of two.
Right shift >> moves bits to the right, dividing by powers of two.

5fill in blank

hard

Fill all three blanks to create a dictionary with keys as numbers, values as bitwise NOT of keys, and filter keys greater than 2.

DSA Python

result = { [1]: [2] for [3] in range(5) if [3] > 2 }

Drag options to blanks, or click blank then click option'

3 left

💡 Hint

Common Mistakes

Using different variable names inconsistently.

Using & or | instead of ~ for NOT operation.

We use num as the loop variable and key.
The value is bitwise NOT of num, written as ~num.
Filter keeps numbers greater than 2.
