Question

Rearrange Numbers in String

Given a string, write a program to re-arrange all the numbers appearing in the string in decreasing order. Note: There will not be any negative numbers or numbers with decimal part.

Input

The input will be a single line containing a string.

Output

The output should be a single line containing the modified string with all the numbers in string re-ordered in decreasing order.

Explanation

For example, if the given string is "I am 5 years and 11 months old", the numbers are 5, 11. Your code should print the sentence after re-ordering the numbers as "I am 11 years and 5 months old".

Sample Input

I am 5 years and 11 months old

Sample Output

I am 11 years and 5 months old

Sample Input

3times4is12

Sample output

12times4is3

Answer 1

user_str = input('Enter your string: ')
numbers = ''.join([i if i.isdigit() else ' ' for i in user_str ]).split()
numbers_rep = list(map(int, numbers))
numbers_rep.sort(reverse = True)
numbers_rep = list(map(str, numbers_rep))
output_str = user_str
# use the problem conditions: not be any numbers with decimal part
for i in numbers:
    output_str = output_str.replace(i,'1.1',1)
for i in numbers_rep:
    output_str = output_str.replace('1.1',i,1)
print(output_str)
