#include 
#include

int main(void)
{
    double c;
    char blank = ' ';

    while((c = getchar()) != EOF)
    {
        if(c == ' ')                                
            {
            putchar(c);                             

                while(( c = getchar() )== ' ')      

                    {
                    if(c != ' ')                    
                    break;
                    }

        if(c == '\t')                               
            {
                putchar(blank);                     
                    while((c = getchar()) == '\t')  

                    {
                    if(c != '\t')                   
                    break;
                    }
            }

    putchar(c);
