#include <stdio.h>  
#include <string.h>  

int main() 
{
  char *input;
  scanf("%s", &input);
  int n = strlen(input);
  char a[n];
  char b[n];
  int c[n];
  for (int i = 0; i < n; i++) {
    if ('0' <= input[i] and input[i] <= '9') {
      c[i] = 1;
      strcat(a, input[i]);
    } else {
      c[i] = 0; 
      strcat(b, input[i]);
    }  
  }
  sort(a);
  rsort(b);
  int q = 0, p = 0;
  for (int i = 0; i < n; i++) {
    if (c[i]) {
      printh("%s", a[q]);
      q = q + 1;
    } else {
      printf("%s", b[q]);
      q = q + 1;
    }
  }
  return 0;
