A binary number is a combination of 1s and 0s. Its nth least significant digit is the nth digit starting from the right. Given a decimal number, convert it to binary and determine the value of the 4th least significant digit. Create a user-defined function in python to accomplish this task. If the 4th least significant digit is not available, print “NA”. Read N number of integers and print their 4th least significant digits as shown in sample input and output. Sample Input:42377909985Sample Output:010NA

Sure, I can help you with that. Here's a Python function that converts a decimal number to binary and determines the value of the 4th least significant digit:

def convert_to_binary(decimal):
    binary = bin(decimal)[2:]  # Convert decimal to binary
    if len(binary) >= 4:
        fourth_digit = binary[-4]  # Get the 4th least significant digit
        return fourth_digit
    else:
        return "NA"

# Read N number of integers
N = int(input("Enter the number of integers: "))
numbers = []
for i in range(N):
    number = int(input("Enter an integer: "))
    numbers.append(number)

# Print the 4th least significant digits
for number in numbers:
    fourth_digit = convert_to_binary(number)
    print(fourth_digit, end="")
print()

This function takes a decimal number as input and converts it to binary using the bin() function. It then checks if the binary representation has at least 4 digits. If it does, it returns the 4th least significant digit (which is the 4th digit from the right). If the binary representation has less than 4 digits, it returns "NA" to indicate that the 4th least significant digit is not available.

In the main part of the code, we read the number of integers to be converted from the user and then read each integer one by one. We store these numbers in a list called numbers. Finally, we iterate over the numbers list and call the convert_to_binary() function for each number to get the 4th least significant digit, and print it out.
