Answer 1

def IsNum(s):
    try:
        int(s)
        return True
    except ValueError:
        return False


s = input()
words = s.split()
numbers = []
for x in words:
    if IsNum(x):
        numbers.append(int(x))
if len(numbers) < 2:
    print(s)
numbers.sort(reverse=True)
result = ''
for x in words:
    if IsNum(x):
        result += str(numbers[0])
        numbers = numbers[1:]
    else:
        result += x
    result += ' '
print(result[:-1])
