Question

To zadanie jest łatwe!

#include <iostream>
#include <string>

int main()
{
	int num;
	std::cin >> num;
	while (num--)
	{
		std::string tag1,tag2;
		std::cin >> tag1 >> tag2;
		std::string train = "";

		for (const auto &i : tag2)
		{
			auto index = tag1.find(i);
			if (index == std::string::npos)
				break;

			train += i;
			tag1.erase(0, index);
		}
		if (train == tag2)
			std::cout << "Tak" << std::endl;
		else
			std::cout << "Nie" << std::endl;
	}
	return 0;
}

#include <iostream>

int main()
{
	unsigned long long a, b, c, s;
	std::cin >> a >> b >> c >> s;

	s *= 100;

	unsigned long long min;
	 
	min = a;
	if (b < a)min = b;
	if (c < b)min = c;

	unsigned a1 = 0, b1 = 0, c1 = 0;

	unsigned count = 0;

	for (auto i = 0;i <= s;i += min)
	{
		a1 += a;
		b1 += b;
		c1 += c;

		if (a1 == b1)
			count++;
		if (a1 == c1)
			count++;
		if (b1 == c1)
			count++;
	}
	std::cout << count;

	return 0;
}

Nie chce gotowych rozwiazan, potrzebuje testow, dla ktorych program zle dziala.
