算法竞赛模板Java版

前言

之前都是使用CPP打算法竞赛，现在使用Java。

为了避免Java繁琐的输入输出，准备了下面的初始模板。

大家有问题和建议可以多多交流

初始模板

import java.io.*;
import java.util.*;
import static java.lang.Math.*;public class Main {// 使用缓冲读和缓冲写加速static BufferedReader br = new BufferedReader(new InputStreamReader(System.in));static PrintWriter out = new PrintWriter(new BufferedWriter(new OutputStreamWriter(System.out)));static StringTokenizer st;public static void solve() throws IOException {// int n = nextInt();// long k = nextLong();// String s = next();// out.println("Hello, Java!");}public static void main(String[] args) throws IOException {// int T = nextInt();int T = 1;while (T-- > 0) {solve();}out.flush();out.close();}// 将一行输入按照空格分词，返回字符串public static String next() throws IOException {while (st == null || !st.hasMoreTokens()) {st = new StringTokenizer(br.readLine());}return st.nextToken();}// 将字符串解析为具体类型public static int nextInt() throws IOException {return Integer.parseInt(next());}public static long nextLong() throws IOException {return Long.parseLong(next());}public static double nextDouble() throws IOException {return Double.parseDouble(next());}// 直接读取一行public static String nextLine() throws IOException {return br.readLine();}
}
