/* ~~~~~UNBEATABLE CHALLENGE~~~~~ WORD PROBLEM :: # 03 You will be given a number and you will need to return it as a string in Expanded Form. For Example: expanded_form(12) # Should return '10 + 2' expanded_form(42) # Should return '40 + 2' expanded_form(70304) # Should return '70000 + 300 + 4' expanded_form(1.24) # Should return '1 + 2/10 + 4/100' expanded_form(7.304) # Should return '7 + 3/10 + 4/1000' expanded_form(0.04) # Should return '4/100' Mandatory : User Input Link your answers in comments No one has completed it yet For more challenges 👇👇👇 https://code.sololearn.com/WudPqFy464fn/?ref=app https://code.sololearn.com/WsUcz8xDUavT/?ref=app For any queries, Please concern me */ #include #include #include #include using namespace std; using SV = string_view; auto whole(SV in, vector& res) { for(size_t i{0}, sz{in.size()}; i < sz; ++i) if(in[i] != '0') res. emplace_back(""s + in[i] + string(sz - i - 1, '0')); } auto frac(SV in, vector& res) { for(size_t i{0}, sz{in.size()}; i < sz; ++i) if(in[i] != '0') res. emplace_back(""s + in[i] + "/1" + string(i+1, '0')); } auto expand(string const& in) { string w, f; stringstream ss{in}; vector res; getline(ss, w, '.'), getline(ss, f, ' '); whole(w, res); frac(f, res); cout << res[0]; for(size_t i{1}, sz{res.size()}; i> in; for(auto&& s : vector{ in, "12", "42", "70304", "0", "1.24", "7.304", "0.0", "0.04"}) { cout << s << " : "; if(s=="0" || s== "0.0") cout << 0 << "\n\n"; else expand(s); } }
