Python Program to print all distinct uncommon digits present in two given numbers
  • Difficulty Level : Medium
  • Last Updated : 22 Mar, 2021

Given two positive integers A and B, the task is to print the distinct digits in descending order, which are not common in the two numbers.

Examples:

Input: A = 378212, B = 78124590
Output: 9 5 4 3 0
Explanation: All distinct digits present in the two numbers are {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}. The digits {1, 2, 6, 7} are common in both numbers.

Input: A = 100, B = 273
Output: 7 3 2 1 0
Explanation: All distinct digits present in the two numbers are {0, 1, 2, 3, 7}. The digits {0, 1, 2, 3, 7} are common in both numbers.

Approach: The problem can be solved using sets, and lists in python. Follow the steps below to solve the problem:



Below is the implementation of the above approach:

Python3




# Python implementation
# of the above approach
  
# Function to print uncommon digits
# of two numbers in descending order
def disticntUncommonDigits(A, B):
  
    # Stores digits of A as string
    A = str(A)
  
    # Stores digits of B as string
    B = str(B)
  
    # Stores the characters
    # of A in a integer list
    lis1 = list(map(int, A))
      
    # Stores the characters
    # of B in a integer list
    lis2 = list(map(int, B))
  
    # Converts lis1 to set
    lis1 = set(lis1)
  
    # Converts lis2 to set
    lis2 = set(lis2)
  
    # Stores the uncommon digits present
    # in the sets lis1 and lis2
    lis = lis1.symmetric_difference(lis2)
  
    # Converts lis to list
    lis = list(lis)
  
    # Sort the list in descending order
    lis.sort(reverse = True)
  
    # Print the list lis
    for i in lis:
        print(i, end =" ")
  
# Driver Code
  
  
# Input
A = 378212
B = 78124590
  
disticntUncommonDigits(A, B)
Output:
9 5 4 3 0

Time Complexity: O(log10(A) + log10(B))
Auxiliary Space: O(log10(A) + log10(B))
