Check if binary representations of two numbers are an anagram
In this tutorial, you will learn to write a Python Program where we can check if the binary representation of two numbers is an anagram. A number is said to be an anagram if both the numbers have the same characters in a different order. Suppose we have two numbers say 9 and 12 then we have to check if the binary representation of these two numbers is an anagram or not. The binary representation of 9 is 1001 and the binary representation of 12 is 1100, so these two are anagrams of each other. Hence, our program should display Yes as output.
Look at the sample input-output format.
The approach to solving this problem is to first convert integer numbers to binary numbers using the
bin() method. Since the length of the binary representation can have different lengths then we will append 0s to make the length equal. We will convert each of the binary strings to a dictionary using
Counter() function. Then we will check if the 0s and 1s in both the dictionary are equal, if they are equal then they are anagram else they are not.
Follow the algorithm to understand the approach better.
Step 1- Import Counter from collections
Step 2- Define a function to check if two binary numbers are anagrams, it will accept two integers as parameters
Step 3- Convert integer numbers to binary numbers using bin()
Step 4- Append zeroes to make the length of binary numbers equal
Step 5- Convert binary string to dictionary
Step 6- Compare if both dictionaries are equal
Step 7- Print yes if they are equal
Step 8- Print no if they are not equal
Step 9- Declare two numbers and pass them in the function
Look at the Python code to understand the implementation. After converting to binary, we have used slicing to remove the first two characters from the string returned by the
bin() method. It returns a string with the prefix '0b', which will be removed using slicing.
from collections import Counter
# convert numbers into binary
bin1 = bin(n1)[2:]
bin2 = bin(n2)[2:]
# append zeros in shorter string
zeros = abs(len(bin1)-len(bin2))
bin2 = zeros * '0' + bin2
bin1 = zeros * '0' + bin1
# convert binary to dictionary
dict1 = Counter(bin1)
dict2 = Counter(bin2)
# compare both dictionaries
if dict1 == dict2:
n1 = 11
n2 = 3
In this tutorial, we have seen how to convert integer to binary and check if the binary representation is an anagram or not. We have used a dictionary to compare characters in the string and check if they are anagrams.
