Java字符串排列算法 题目:现有ABCDE 5个球 构成的排列组合 可重复抽取 最多取到16个 共有多少种组合方式? 比如:取1个球可以构成的组合有 A B C D E 共5种,取2个球可以构成的组合有 5+4+3+2+1=15种 (BA 和 AB 这种重复的排列 算成一种) AA AB AC AD AE BB BC BD BE CC CD CE DD DE EE 取 3 个球可以构成的组合是 (5+4+3+2+1)+(4+3+2+1)+(3+2+1)+(2+1)+1= 35种 AAA AA
java大数还是很好用的! 基本加入: import java.math.BigInteger; import jave.math.BigDecimal; 分别是大数和大浮点数. 首先读入可以用: Scanner input = new Scanner(System.in); BigInteger a = input.nextBigInteger(); 这样读还是很方便的 当然还有自己创建: BigInteger a = new BigInteger("1"); int b=1; Bi
java大数是个好东西,用起来方便,代码短. 代码如下: import java.util.*; import java.math.*; public class Main { public static void main(String args[]) { Scanner cin = new Scanner(System.in); BigInteger a , b; while(cin.hasNext()) { a = cin.nextBigInteger(); b = cin.nextBig
