93. Rearrange Digits for Extremes

Write a Python program that takes an integer and rearranges the digits to create two maximum and minimum numbers.

Sample Solution-1:

Python Code:

def test(n):
    temp = []
    for e in str(n):
        temp.append(e)
        max_num = "".join(sorted(temp)[::-1])
        min_num = "".join(sorted(temp))        
    return int(max_num), int(min_num)
                                      
n = 1254
print("Original number:", n)
print("Rearrange the digits of the said number to get Maximum and Minimum numbers:")
print("Maximum and Minimum Numbers:",test(n))
n = 6
print("\nOriginal number:", n)
print("Rearrange the digits of the said number to get Maximum and Minimum numbers:")
print("Maximum and Minimum Numbers:",test(n))
n = 1000
print("\nOriginal number:", n)
print("Rearrange the digits of the said number to get Maximum and Minimum numbers:")
print("Maximum and Minimum Numbers:",test(n))

Sample Output:

Original number: 1254
Rearrange the digits of the said number to get Maximum and Minimum numbers:
Maximum and Minimum Numbers: (5421, 1245)

Original number: 6
Rearrange the digits of the said number to get Maximum and Minimum numbers:
Maximum and Minimum Numbers: (6, 6)

Original number: 1000
Rearrange the digits of the said number to get Maximum and Minimum numbers:
Maximum and Minimum Numbers: (1000, 1)

Sample Solution-2:

Python Code:

def test(n):
    temp = ''.join(sorted(str(n)))
    return int(temp[::-1]), int(temp) 
                                      
n = 1254
print("Original number:", n)
print("Rearrange the digits of the said number to get Maximum and Minimum Numbers:")
print("Maximum and Minimum Numbers:",test(n))
n = 6
print("\nOriginal number:", n)
print("Rearrange the digits of the said number to get Maximum and Minimum Numbers:")
print("Maximum and Minimum Numbers:",test(n))
n = 1000
print("\nOriginal number:", n)
print("Rearrange the digits of the said number to get Maximum and Minimum Numbers:")
print("Maximum and Minimum Numbers:",test(n))

Sample Output:

Original number: 1254
Rearrange the digits of the said number to get Maximum and Minimum Numbers:
Maximum and Minimum Numbers: (5421, 1245)

Original number: 6
Rearrange the digits of the said number to get Maximum and Minimum Numbers:
Maximum and Minimum Numbers: (6, 6)

Original number: 1000
Rearrange the digits of the said number to get Maximum and Minimum Numbers:
Maximum and Minimum Numbers: (1000, 1)
