问题描述


 小蓝发现了一个有趣的数列,这个数列的前几项如下:

 1,1,2,1,2,3,1,2,3,4,...

 小蓝发现,这个数列前 1 项是整数 1 ,接下来 2 项是整数 1 至 2 接下来 3 项是整数 1 至 3 接下来 4 项是整数 1 至 4 ,依次类推。

 小蓝想知道,这个数列中,连续一段的和是多少。


输入格式


 输入的第一行包含一个整数 T ,表示询问的个数。

 接下来 T 行,每行包含一组询问,其中第 i 行包含两个整数 li和 ri,表示询问数列中第 li个数到第 ri个数的和。


输出格式


 输出 T 行,每行包含一个整数表示对应询问的答案。

H、异或变换(源码提供者:学生【郭尚】)

时间限制: 3.0s 内存限制: 512.0MB 本题总分:20 分


问题描述


 小蓝有一个 01 串 s = s1s2s3 ⋅ ⋅ ⋅ sn。

 以后每个时刻,小蓝要对这个 01 串进行一次变换。每次变换的规则相同。

 对于 01 串 s = s1s2s3 ⋅ ⋅ ⋅ sn,变换后的 01 串s' = s'1s'2s'3 ⋅ ⋅ ⋅ s'n为:

 s'1=s1;    

 s'i=si-1⊕si。

 其中 a ⊕ b 表示两个二进制的异或,当 a 和 b 相同时结果为 0 ,当 a 和 b

 不同时结果为 1。

 请问,经过 t 次变换后的 01 串是什么?


输入格式


 输入的第一行包含两个整数 n,t,分别表示 01 串的长度和变换的次数。

 第二行包含一个长度为 n 的 01 串。


输出格式


 输出一行包含一个 01 串,为变换后的串。


测试样例1

Input:

5 3

10110


Output:

11010


Explanation:

初始时为 10110,变换 1 次后变为 11101,变换 2 次后变为 10011,变换 3 次后变为 11010。


评测用例规模与约定


 对于 40% 的评测用例,1 ≤ n ≤ 100 , 1 ≤ t ≤ 1000。

 对于 80% 的评测用例,1 ≤ n ≤ 1000 , 1 ≤ t ≤ 10^9。

 对于所有评测用例,1 ≤ n ≤ 10000 , 1 ≤ t ≤ 10^18。


package action;
import java.util.Scanner;
public class demo {
  public static void main(String[] args) {
  Scanner sc = new Scanner(System.in);
  int n = sc.nextInt();
  long t = sc.nextInt();// 变换次数
  StringBuilder as = new StringBuilder();// 输出得变量
  char[] c = sc.next().toCharArray();// 一个长度为n得字符串转数组
  sc.close();
  for (int i = 0; i < n; i++) {
    boolean a = c[i] == '0';// true是0
    // 在n里面判断是否相等
    for (int j = 1; i - j >= 0 && j <= t; j++)
    if ((t & j) == j && c[i - j] == '1')
      a = !a;
    as.append(a ? 0 : 1);// 三目运算,相等是0,不相等是1
  }
  System.out.println(as);
