1042. Shuffling Machine 解析

本文介绍了一种通过指定位置重新排列元素的洗牌算法实现过程。使用C++编程语言完成了一个包含54张扑克牌(包括两张鬼牌)的牌组初始化,并通过多次迭代将牌组元素按给定的新位置进行重新排列。

看了半天发现是在洗牌。。。。。

看清楚题目,给出的位置是把当前位置的元素放到那个位置去。应该就没事了。

#include <iostream>
#include <string>

#define SIZE 55

using namespace std;



string Orig[SIZE], Relt[SIZE];
int shuf[SIZE];
int n;




string int2str(int n) {
	string s;
	if (n > 0 && n < 10) {
		s.push_back('0' + n);	
	}
	else {
		s.push_back('1');
		s.push_back('0' + n % 10);
	}
	return s;
}

void Init() {
	
	int c = 1;
	for (int i = 1; i <= 13; i++,c++) {
		Orig[c] = "S";
		Orig[c] += int2str(i);
	}
	for (int i = 1; i <= 13; i++, c++) {
		Orig[c] = "H";
		Orig[c] += int2str(i);
	}
	for (int i = 1; i <= 13; i++, c++) {
		Orig[c] = "C";
		Orig[c] += int2str(i);
	}
	for (int i = 1; i <= 13; i++, c++) {
		Orig[c] = "D";
		Orig[c] += int2str(i);
	}
	Orig[c++] = "J1";
	Orig[c++] = "J2";
	
}

void shuff() {
	for (int i = 0; i < n; i++) {
		for (int j = 1; j < SIZE; j++) {
			Relt[shuf[j]] = Orig[j];
		}

		for (int j = 1; j < SIZE; j++) {
			Orig[j] = Relt[j];
		}
	}
}

int main() {

	cin >> n;

	for (int i = 1; i < SIZE; i++) {
		cin >> shuf[i];
//		cout << i << " " << shuf[i] << endl;
	}


	Init();
	shuff();

	for (int i = 1; i < SIZE -1; i++) {
		cout << Relt[i] << " ";
	}
	cout << Relt[SIZE - 1] << endl;
	

	system("pause");
	
	return 0;
}


A shuffling machine in C++ can be implemented using an array to represent the deck of cards and using the random number generator to shuffle the cards. Here is a sample code for a shuffling machine: ``` #include <iostream> #include <cstdlib> #include <ctime> using namespace std; const int NUM_CARDS = 52; class ShufflingMachine { private: int deck[NUM_CARDS]; int position; public: ShufflingMachine() { for (int i = 0; i < NUM_CARDS; i++) { deck[i] = i; } position = 0; } void shuffle() { srand(time(NULL)); for (int i = 0; i < NUM_CARDS; i++) { int j = rand() % NUM_CARDS; swap(deck[i], deck[j]); } position = 0; } int dealCard() { if (position >= NUM_CARDS) { shuffle(); } return deck[position++]; } }; int main() { ShufflingMachine shuffler; shuffler.shuffle(); for (int i = 0; i < NUM_CARDS; i++) { cout << shuffler.dealCard() << " "; } cout << endl; return 0; } ``` In this code, the `ShufflingMachine` class represents the shuffling machine. The `deck` array stores the deck of cards, and the `position` variable keeps track of the current position in the deck. The `shuffle` method shuffles the deck by randomly swapping cards. It uses the `srand` function to seed the random number generator with the current time, and the `rand` function to generate random indices for swapping cards. The `dealCard` method deals the next card from the deck. If the deck has been exhausted, it calls the `shuffle` method to shuffle the cards again. In the `main` function, we create a `ShufflingMachine` object and shuffle the cards. Then we deal all the cards and print them out.
