英文字母

import java.util.Scanner;

public class 英文字母 {
    public static void main(String[] args) {
        char[] cr = new char[26];
        for (int i = 65; i < 65+26; i++) {
            char daxie = (char)i;
            int ci = i-65;
            cr[ci] = daxie;
//            System.out.println(cr[ci]);
        }
        Scanner sc = new Scanner(System.in);
        int n = sc.nextInt();
        int i = n - 1;
        System.out.println(cr[i]);


    }
}

当然也可以这样

char zimu[]={
'Z','A','B','C','D','E','F','G','H',
'I','J','K','L','M','N','O','P','Q',
'R','S','T','U','V','W','X','Y'};

单词分析

package textDemo;

import java.util.Scanner;

public class 单词分析 {
    public static void main(String[] args) {
        int[] a = new int[26];
        Scanner sc = new Scanner(System.in);
        String str = sc.next();
        for (int i = 0; i < str.length(); i++) {
            a[str.charAt(i) - 'a']++;

        }
        int max = 0;
        char ch = 'a';
        for (int i = 0; i < 26; i++) {
            if (a[i] > max){
                max = a[i];
                ch = (char) ('a'+i);

            }
        }
        System.out.println(ch);
        System.out.println(max);

    }
}

火星旅行

one老师可能还咩有起床,我的只有16%的样例是通过了的

package textDemo;

import java.util.Scanner;

public class 火星旅行 {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        int n = sc.nextInt();
        int[] p = new int[n];
        int[] d = new int[n];
        for (int i = 0; i < n; i++) {
            p[i] = sc.nextInt();
            d[i] = sc.nextInt();

        }
        for (int i = 0; i < n; i++) {
//            System.out.println(p[i]+"he"+d[i]);
            if (p[i] > d[i]) {
                System.out.println("TAK");
            } else {
                System.out.println("NTE");
            }
        }

    }
}
