题目描述 Bessie's cruel second grade teacher has assigned a list of N (1 <= N <= 100) positive integers I (1 <= I <= 10^60) for which Bessie must determine their parity (explained in second grade as 'Even... or odd?'). Bessie is overwhelmed by the…

描述 Q先生是一个热爱学习的男孩子. 他认为一个 n 位的正整数 x 若能被称作是绚丽多彩的,一定要满足对于{1,3,5,7,9} 中任意一个奇数或者没有在 x 中出现,或者在 x 中出现了恰好奇数次:同时对于 {0,2,4,6,8} 中任意的偶数或者没有在 x 中出现,或者在x 中出现了偶数次.同时需要注意 x 是不能有前导零的. 例如 141221242 就是一个九位的绚丽多彩的数. 现在Q先生给定了正整数 n 与另外一个正整数 p,希望你统计出来一共有多少不超过 n 位的绚丽多彩的数,并输…
需求说明: 定义两个方法,在控制台输入一个数字,这两个方法可以求出1到该数字之间所有偶数之和.奇数之和,并将对应结果和返回.在main方法中调用该方法,并在控制台打印出结果.(有参数有返回值方法) 运行效果如图所示: 实现思路: import java.util.Scanner; import javax.xml.soap.Text; public class EvenOdd { public static int even(int num,int sum) { System.out.print…
[抄题]: You are given an array A of strings. Two strings S and T are special-equivalent if after any number of moves, S == T. A move consists of choosing two indices i and j with i % 2 == j % 2, and swapping S[i] with S[j]. Now, a group of special-equi…
