Write Emacs Lisp scripts to

(a) Insert today’s date into the current buffer at the insertion point (current cursor location).

(b) Place quote marks (" ") around the word surrounding the insertion point.

(c) Fix end-of-sentence spaces in the current buffer. Use the following heuristic: if a period, question mark, or exclamation point is followed by a single space (possibly with closing quote marks, parentheses, brackets, or braces in-between), then add an extra space, unless the character preceding the period, question mark, or exclamation point is a capital letter (in which case we assume it is an abbreviation).

(d) Run the contents of the current buffer through your favorite spell checker, and create a new buffer containing a list of misspelled words.

(e) Delete one misspelled word from the buffer created in (d), and place the cursor (insertion point) on top of the first occurrence of that misspelled word in the current buffer.
