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

Answer 1

def RearrangeNumbers(source):
    tmp0 = list(source)
    tmp1 = [c if c.isdigit() else ' ' for c in tmp0 ]
    tmp2 = "".join(tmp1)
    tmp3 = tmp2.split()
    numbers = []
    for w in tmp3:
        numbers.append(int(w))
    if len(numbers) < 2:
        return source
    numbers.sort(reverse=True)
    result_string = ''
    i = 0
    while i < len(source): 
        c = source[i]
        if not c.isdigit():
            result_string += c
        else:
            result_string += str(numbers[0])
            numbers = numbers[1:]
            while source[i].isdigit():
                i+=1
            result_string += source[i]
        i+=1
    return result_string

print(RearrangeNumbers(input()))
