/* Longest Sequence Given a series of numbers, find the longest sequence in the series. A sequence could be one of the following: An ascending sequence Example: Input: 836926 Output: 369 A descending sequence Example: Input: 2995316 Output: 9531 An equal sequence Example: Input: 255566 Output: 555 Write a program that reads a series of numbers from the input and finds the longest ascending, descending or equal sequence in the series. https://www.sololearn.com/learn/4743/?ref=app */ #include #include #include #include using namespace std; template vector process_lst(string str,Compf cmpf) { vector num_list; size_t j{0}; for(auto i{1u};i> str; cout << "Input sequence = " << str <<'\n'; auto maxe = [](auto const& lst) { return *max_element(begin(lst),end(lst),[](auto const& lhs, auto const& rhs){ return lhs.size() < rhs.size(); }); }; // ascending auto lst = process_lst(str,less_equal()); cout << "Longest ascending : "; Result(lst, maxe(lst)); // descending lst = process_lst(str,greater_equal()); cout << "Longest descending : "; Result(lst, maxe(lst)); // equal lst = process_lst(str,not_equal_to()); cout << "Longest equal : "; Result(lst, maxe(lst)); }
