摘要：先java代码：import java.util.Scanner;import java.math.*;public class Main { public static void main(String[] args) { Scanner cin = new Scanner(System.in); BigInteger fb[] = new BigInteger [1005]; fb[1] = BigInteger.valueOf(1); fb[2] = BigInteger.valueOf(1); for (int i = 3; i int fb[1001][100];void ... 阅读全文

摘要：刚刚开始用Java，代码难免不够简洁。import java.math.BigDecimal;import java.util.Scanner;public class Main { public static void main(String[] args) { Scanner cin = new Scanner(System.in); while (cin.hasNext()) { BigDecimal a = cin.nextBigDecimal(); BigDecimal b = cin.nextBigDecimal(); a = a.add(b); if (a.c... 阅读全文

摘要：虽然题目那么长其实就是把8进制的浮点数转换成10进制，为了练习Java Biginteger 类 我这里用的是Java，也可以用数组模拟。import java.math.BigDecimal;import java.math.RoundingMode;import java.util.Scanner;public class Main { public static void main(String[] args) { Scanner cin = new Scanner(System.in); String str, ors; BigDecimal x, y, z; while (c... 阅读全文
