Hint
Remember to use getchar() to read ‘\n‘ after the interger T, then you may use gets() to read a line and process it.
 

#include<stdio.h>
#include<string.h>
char s[1002];
int main()
{
	int test,i,j,len,k;
	scanf("%d",&test);
	getchar();
	while(test--)
	{
		gets(s);
		len=strlen(s);
		for(i=0,k=0;i<len;i++)
		{
			if(s[i]==' ')
			{
			   for(j=i-1;j>=k;j--)
			   {
			   	   printf("%c",s[j]);
			   }
			   printf(" ");
                k=i+1;
		    }
		}
		for(j=len-1;j>=k;j--)
		    printf("%c",s[j]);
		printf("\n");
	}
	return 0;
}
