Answer

here's an example Python program that takes two bit strings of length n from the user and calculates the bitwise AND, bitwise OR, and bitwise XOR of those strings In this program, the len() function is used to determine the length of the bit strings entered by the user. The program then calculates the bitwise AND, bitwise OR, and bitwise XOR of the bit strings by iterating through each bit in the strings and applying the appropriate logical operations. Finally, the program prints the results of these calculations.

Work Step by Step

# Take input from user for the bit strings and the length of the strings bit_string_1 = input("Enter the first bit string: ") bit_string_2 = input("Enter the second bit string: ") n = len(bit_string_1) # Calculate the bitwise AND, bitwise OR, and bitwise XOR of the bit strings bitwise_and = "" bitwise_or = "" bitwise_xor = "" for i in range(n): if bit_string_1[i] == "1" and bit_string_2[i] == "1": bitwise_and += "1" else: bitwise_and += "0" if bit_string_1[i] == "0" and bit_string_2[i] == "0": bitwise_or += "0" else: bitwise_or += "1" if bit_string_1[i] != bit_string_2[i]: bitwise_xor += "1" else: bitwise_xor += "0" # Print the bitwise AND, bitwise OR, and bitwise XOR of the bit strings print("Bitwise AND:", bitwise_and) print("Bitwise OR:", bitwise_or) print("Bitwise XOR:", bitwise_xor)
