In the previous article, we have discussed Python Program to Toggle Bits of a Number Except First and Last bits

Given a number and the task is to print all the bitwise AND set of a given number.

For some number I the bitwise AND set of a number N is all feasible numbers x smaller than or equal to N such that N & I equals x.

**Examples:**

**Example1:**

**Input:**

Given Number = 6

**Output:**

The all bitwise AND set of a given number{ 6 } : 0 2 4 6

**Explanation:**

Iterating from 0 to 6 so 0 & 6 = 0 1 & 6 = 0 2 & 6 = 2 3 & 6 = 2 4 & 6 = 4 5 & 6 = 4 6 & 6 = 6 Hence the all bitwise AND set of a given number = 0 2 4 6 (removing duplicates)

- Python Program to Find Whether a Number is a Power of Two

**Example2:**

**Input:**

Given Number = 3

**Output:**

The all bitwise AND set of a given number{ 3 } : 0 1 2 3

## Program Print Bitwise AND set of a Number N in Python

Below are the ways to print all the bitwise AND set of a given number in Python:

- Using For Loop (Static Input)
- Using For loop (User Input)
- Using While Loop (Static Input)
- Using While loop (User Input)

### Method #1: Using For Loop (Static Input)

**Approach:**

- Give the number as static input and store it in a variable.
- Loop till the given number using the for loop.
- Inside the Loop, apply AND operation for the given number and the iterator value and store it in another variable.
- Check if the above result is equal to the iterator value using the if conditional statement.
- If the statement is true, then print the iterator value separated by spaces.
- The Exit of the Program.

**Below is the implementation:**

# Give the number as static input and store it in a variable. gvn_numb = 6 # Loop till the given number using the for loop. print("The all bitwise AND set of a given number{", gvn_numb, "} : ") for itr in range(gvn_numb + 1): # Apply AND operation for the given number and the iterator value and store it in # another variable. p = gvn_numb & itr # Check if the above result is equal to the iterator value using the if conditional # statement. if (p == itr): # If the statement is true, then print the iterator value separated by spaces. print(itr, " ", end="")

**Output:**

The all bitwise AND set of a given number{ 6 } : 0 2 4 6

### Method #2: Using For loop (User Input)

**Approach:**

- Give the number as user input using the int(input()) function and store it in a variable.
- Loop till the given number using the for loop.
- Inside the Loop, apply AND operation for the given number and the iterator value and store it in another variable.
- Check if the above result is equal to the iterator value using the if conditional statement.
- If the statement is true, then print the iterator value separated by spaces.
- The Exit of the Program.

**Below is the implementation:**

# Give the number as user input using the int(input()) function and # store it in a variable. gvn_numb = int(input("Enter some random number = ")) # Loop till the given number using the for loop. print("The all bitwise AND set of a given number{", gvn_numb, "} : ") for itr in range(gvn_numb + 1): # Apply AND operation for the given number and the iterator value and store it in # another variable. p = gvn_numb & itr # Check if the above result is equal to the iterator value using the if conditional # statement. if (p == itr): # If the statement is true, then print the iterator value separated by spaces. print(itr, " ", end="")

**Output:**

Enter some random number = 3 The all bitwise AND set of a given number{ 3 } : 0 1 2 3

### Method #3: Using While Loop (Static Input)

**Approach:**

- Give the number as static input and store it in a variable.
- Assign the given number to the variable say
**tempry**. - Loop till the above variable
**tempry**is not equal to 0 using the while loop. - Inside the Loop, Print the value of
**tempry**separated by spaces. - Apply AND operation for the
**tempry -1**and given number and store it in the same variable**tempry.** - Exit the loop.
- Print 0.
- The Exit of the Program.

**Below is the implementation:**

# Give the number as static input and store it in a variable. gvn_numb = 10 # Assign the given number to the variable say tempry. tempry = gvn_numb print("The all bitwise AND set of a given number{", gvn_numb, "} : ") # Loop till the above variable tempry is not equal to 0 using the while loop. while(tempry != 0): # Inside the Loop, Print the value of tempry separated by spaces. print(tempry, end=" ") # Apply AND operation for the tempry -1 and given number and store it in the same variable # tempry. tempry = (tempry - 1) & gvn_numb # Exit the loop. # Print 0. print("0")

**Output:**

The all bitwise AND set of a given number{ 10 } : 10 8 2 0

### Method #4: Using While loop (User Input)

**Approach:**

- Give the number as user input using the int(input()) function and store it in a variable.
- Assign the given number to the variable say
**tempry**. - Loop till the above variable
**tempry**is not equal to 0 using the while loop. - Inside the Loop, Print the value of
**tempry**separated by spaces. - Apply AND operation for the
**tempry -1**and given number and store it in the same variable**tempry.** - Exit the loop.
- Print 0.
- The Exit of the Program.

**Below is the implementation:**

# Give the number as user input using the int(input()) function and store it in a variable. gvn_numb = int(input("Enter some random number = ")) # Assign the given number to the variable say tempry. tempry = gvn_numb print("The all bitwise AND set of a given number{", gvn_numb, "} : ") # Loop till the above variable tempry is not equal to 0 using the while loop. while(tempry != 0): # Inside the Loop, Print the value of tempry separated by spaces. print(tempry, end=" ") # Apply AND operation for the tempry -1 and given number and store it in the same variable # tempry. tempry = (tempry - 1) & gvn_numb # Exit the loop. # Print 0. print("0")

**Output:**

Enter some random number = 7 The all bitwise AND set of a given number{ 7 } : 7 6 5 4 3 2 1 0
