苦逼 最后5分钟断网 死活登不上去了 不知道第二道编程提交成功没有 倒霉的人
第一题AC
import java.util.Scanner;
import java.util.regex.Pattern;
public class Main{
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
int i = scanner.nextInt();
String[] strings = new String[i];
for (int j = 0; j < i; j++) {
strings[j] = scanner.next();
}
int count = count(strings);
System.out.println(count);
}
private static int count(String[] strings) {
int num = 0;
for (String string : strings) {
if (Pattern.matches("[a-zA-Z]+", string) && string.length() <= 10) {
num++;
}
}
return num;
}
} 第二题 不知道是不是AC 最后断网没看到结果 idea上测试是OK的（苦逼ing） import java.util.Scanner;
public class Main {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
String s1 = scanner.nextLine();
String[] strings = s1.split(" ");
int N = Integer.parseInt(strings[0]);
int M = Integer.parseInt(strings[1]);
String s2 = scanner.nextLine();
String[] strings2 = s2.split(" ", M);
String res = change(N, M, strings2);
System.out.println(res);
}
private static String change(int n, int m, String[] strings2) {
String[] str = new String[n];
for (int i = 0; i < n; i++) {
str[i] = String.valueOf(i + 1);
}
for (String s : strings2) {
if (s.equals("1")){
String temp = str[0];
for (int i = 0; i < str.length-1; i++) {
str[i] = str[i+1];
}
str[str.length-1] = temp;
}else {
str = swap(str);
for (int i = 0; i < str.length; i++) {
str[i] = str[i];
}
}
}
StringBuilder stringBuilder = new StringBuilder();
for (String s : str) {
stringBuilder.append(s+" ");
}
return stringBuilder.toString();
}
private static String[] swap(String[] strings1) {
for (int i = 0; i <= strings1.length/2; ) {
if (strings1[i].equals("")){
continue;
}
String temp = strings1[i];
strings1[i] = strings1[i+1];
strings1[i+1] = temp;
i+=2;
}
return strings1;
}
}
