Python 程式檢查兩個數字的二進位制表示是否是變位詞。

給出兩個數字。我們的任務是檢查它們是否是二進位制表示上的變位詞。我們可以使用 Counter（可迭代）方法和字典比較在 python 中快速解決此問題。

示例

Input: a = 8, b = 16 
Output : Yes
Binary representations of both numbers have same 0s and 1s.

演算法

Step 1 : Given two numbers.
Step 2 : Convert both number into its binary using bin() function and remove first two characters because of bin().
Step 3 : Since binary representation of both numbers could differ in length so we will append zeroes in start of   shorter string to make both string of equal length.
Step 4 : Compare both dictionaries, if value of 0’s and 1’s in both dictionaries are equal then binary representations of two numbers are anagram otherwise not. Binary representations into dictionary.

示例程式碼

# function to Check if binary representations 
# of two numbers are anagram 
from collections import Counter 

def anagramoftwonumber(p1,p2): 
   # convert numbers into in binary 
   # and remove first two characters of  
   # output string because bin function  
   #'0b' as prefix in output string 
   bno1 = bin(p1)[2:] 
   bno2 = bin(p2)[2:] 
  
   # append zeros in shorter string 
   zeros = abs(len(bno1)-len(bno2)) 
   if (len(bno1)>len(bno2)): 
      bno2 = zeros * '0' + bno2 
   else: 
      bno1 = zeros * '0' + bno1 
  
   # convert binary representations  
   # into dictionary 
   dict1 = Counter(bno1) 
   dict2 = Counter(bno2) 
  
   # compare both dictionaries 
   if dict1 == dict2: 
      print(p1, p2 ,"are two anagram number") 
   else: 
      print(p1 , p2 ,"are not anagram number") 
  
# Driver program 
if __name__ == "__main__": 
   n1 = int(input("Enter First number ::>"))
   n2 = int(input("Enter Second number ::>"))
   anagramoftwonumber(n1,n2)

輸出

Enter First number ::>8
Enter Second number ::>16
8 16 are two anagram number

Enter First number ::>3
Enter Second number ::>2
3 2 are not anagram number
