Write a class that has three unsigned members representing year, month, and day. Write a constructor that takes a string representing a date. This constructor should handle a variety of formats, such as January 1, 1900, 1/1/1900, Jan 1, 1900, and so on.

#include "date.h"

Determine whether one of the two vectors of ints is the prefix of the other.

	#include <iostream>
	#include <vector>

	typedef std::vector<int> int_vec;

	// the size of ivec1 is less than or equal to the size of ivec2
	static bool is_prefix_impl(const int_vec& ivec1, const int_vec& ivec2)
	{
	auto it1 = ivec1.begin();
	auto it2 = ivec2.begin();

Keep track of the largest number of times a single repetition occurs and which word is repeated.

	#include <iostream>
	#include <string>

	int main(int arc, char* argv[])
	{
	int max_count = 0;
	std::string max_count_word;

	int count = 0;
	std::string prev_word;
