A) Utilize an external CSS file to implement the following in your pages: . All text for <p> elements with class selector hidden within element have blue background and text will not be displayed/shown. The space between the content and the border is 20px.

All <li> elements (children of a <ul> with id selector horizontal) will be displayed in one ine and the size of the text will be 2 times larger than the default size.

Explain briefly why you cannot expect to find a previous version of every file with which you work.

What is the worst-case complexity of the maxrepeats function? assume that the longest string in the names array is at most 25 characters wide (i.e., string comparison can be treated as o( class namecounter { private: int* counts; int nc; string* names; int nn; public: namecounter (int ncounts, int nnames); int maxrepeats() const; }; int namecounter: : maxrepeats () { int maxcount = 0; for (int i = 0; i < nc; ++i) { int count = 1; for (int j = i+1; j < nc; ++j) { if (names[i] == names[j]) ++count; } maxcount = max(count, maxcount); } return maxcount; }
