Write a C program to take n files containing strings in ascending order (no duplicates within a file) and produce a file out. dat containing a line for each string (in ascending order). Even if a string str appears in multiple files, it should be output only once and, for each string, you should also output the number of files (k) containing the string. This should be done using code similar to: fprintf(outfp,"%s %d\n",str, k);

Scientists have changed the model of the atom as they have gathered new evidence. one of the atomic models is shown below. what experimental evidence led to the development of this atomic model from the one before it? a few of the positive particles aimed at a gold foil seemed to bounce back. the colors of light emitted from heated atoms had very specific energies. experiments with water vapor showed that elements combine in specific proportions. cathode rays were bent in the same way whenever a magnet was brought near them.
