Question

Can you please rewrite replacing the vector<vector<int>> all_line_numbers; that was removed and remove a difference vector that will preform a parallel sort please. Thank you

Rewrite the program without the unnecessary vector.

1) The program declares the following vectors,

vector<string> all_words;
vector<int> all_word_counts;
vector<vector<int>> all_line_numbers; //do not remove this one

One of the vectors is unnecessary.

2) Sort the 2 or 3 parallel vectors in ascending order of the words or the number of times the words appear in the file.
