On the reading-corner shelf labels, every word of a book title starts with a capital. Write title_case(title): words are separated by one space; make the first letter of each a capital and leave the rest alone. An empty title stays empty.

Examples

title_case("the little prince")→'The Little Prince'

title_case("")→''

The functionstring title_case(string title)

main.cpp

#include <string>
#include <cctype>
using namespace std;

string title_case(string title) {
    for (int i = 0; i < title.size(); i++) {
        // your code here: at the start or after a space, make title[i] a capital
    }
    return title;
}
