In the previous article, we have discussed Python Program to Find Sum of Modulo K of First N Natural Numbers

Given two numbers x, y(integers) and the task is to find the value of given y modulus 2 raised to the power x.

**Examples:**

**Example1:**

**Input:**

Given x value = 5 Given y value = 9

**Output:**

The result of given y modulus 2 raised to the power x = 9

**Example2:**

**Input:**

Given x value = 3 Given y value = 12

**Output:**

The result of given y modulus 2 raised to the power x = 4

## Program to Find Value of y Mod (2 raised to power x) in python

Below are the ways to find the value of given y modulus 2 raised to the power x in python:^{ }

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

**Approach:**

- Give the number x as static input and store it in a variable.
- Give the number y as static input and store it in another variable.
- Pass the given two numbers y and x as the arguments to the
**y_mod2powx**function. - Create a function to say
**y_mod2powx**which takes the given two numbers y and x as the arguments and returns the value of given y modulus 2 raised to the power x. - Calculate the value of 2 raised to the power x using the pow() function and store it in a variable.
- Calculate the value of the given y value modulus the above result and store it in another variable
**rslt**. - Return the above result value
**rslt**. - Print the value of given y modulus 2 raised to the power x.
- The Exit of the Program.

**Below is the implementation:**

# Create a function to say y_mod2powx which takes the given two numbers y and x as # the arguments and returns the value of given y modulus 2 raised to the power x. def y_mod2powx(gvn_yval, x): # Calculate the value of 2 raised to the power x using the pow() function and store it # in a variable. p = pow(2, gvn_xval) # Calculate the value of the given y value modulus the above result and store it in # another variable rslt. rslt = gvn_yval % p # Return the above result value rslt. return (rslt) # Give the number x as static input and store it in a variable. gvn_xval = 5 # Give the number y as static input and store it in another variable. gvn_yval = 9 # Pass the given two numbers y and x as the arguments to the y_mod2powx function. # Print the value of given y modulus 2 raised to the power x. print("The result of given y modulus 2 raised to the power x =", y_mod2powx(gvn_yval, gvn_xval))

**Output:**

The result of given y modulus 2 raised to the power x = 9

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

**Approach:**

- Give the number x as user input using the int(input()) function and store it in a variable.
- Give the number y as user input using the int(input()) function and store it in another variable.
- Pass the given two numbers y and x as the arguments to the
**y_mod2powx**function. - Create a function to say
**y_mod2powx**which takes the given two numbers y and x as the arguments and returns the value of given y modulus 2 raised to the power x. - Calculate the value of 2 raised to the power x using the pow() function and store it in a variable.
- Calculate the value of the given y value modulus the above result and store it in another variable
**rslt**. - Return the above result value
**rslt**. - Print the value of given y modulus 2 raised to the power x.
- The Exit of the Program.

**Below is the implementation:**

# Create a function to say y_mod2powx which takes the given two numbers y and x as # the arguments and returns the value of given y modulus 2 raised to the power x. def y_mod2powx(gvn_yval, x): # Calculate the value of 2 raised to the power x using the pow() function and store it # in a variable. p = pow(2, gvn_xval) # Calculate the value of the given y value modulus the above result and store it in # another variable rslt. rslt = gvn_yval % p # Return the above result value rslt. return (rslt) # Give the number x as user input using the int(input()) function and # store it in a variable. gvn_xval = int(input("Enter some random number = ")) # Give the number y as user input using the int(input()) function and # store it in another variable. gvn_yval = int(input("Enter some random number = ")) # Pass the given two numbers y and x as the arguments to the y_mod2powx function. # Print the value of given y modulus 2 raised to the power x. print("The result of given y modulus 2 raised to the power x =", y_mod2powx(gvn_yval, gvn_xval))

**Output:**

Enter some random number = 3 Enter some random number = 12 The result of given y modulus 2 raised to the power x = 4
