#include <iostream>

int main(int argc, const char *argv[]) 
    char a[100];
    gets(a);
    int i, j, temp;
    for (j = 0; j < strlen(a); j++) 
        for (i = 0; i < strlen(a) - 1 - j; i++) 
            if (a[i] >= 'a' && a[i] <= 'z')
                a[i] -= 32;
            else if (a[i] >= 'A' && a[i] <= 'Z')
                a[i] += 32;
            
            if (a[i] < a[i + 1]) 
                temp     = a[i];
                a[i]     = a[i + 1];
                a[i + 1] = temp;
            
        
        printf("%c", a[i]);
    
    return 0;
