{
	while(n>=i)

	if((i%a) == 0 && !((i%b) == 0))ca++;
 	if((i%b) == 0 && !((i%a) == 0))cb++;
	//printf("t=%d n=%d i=%d i<=n=%d a=%d b=%d (i/a)=%d (i/b)=%d ca=%d cb=%d\n",t,n,i,(n>=i),a,b,(i%a),(i%b),ca,cb);
	i++;
	}

}	
printf("ca=%d cb=%d\n",ca,cb);
if((ca+cb)>=k)
printf("Win\n");
else 
printf("Lose\n");
j++;
}
return 0;

Print only what is specified in the input output format. Also, initialise i, ca, cb inside the t loop, everytime.

Also, refer to this for the second subtask.
