题目描述:

多组数据，每组输入一串字符串，对于输入的每个字符串，查找其中的最大字母，并在该字母后面插入字符串“(DJTU)”。

代码:

package lanqiao;import java.util.*;
public class Main {public static void main(String[] args) {Scanner sc = new Scanner(System.in);int[] a = new int[101];String str = "(DJTU)";while(sc.hasNext()){String s = sc.nextLine();char[] c = s.toCharArray();int cnt = 0;char max = 0;for(int i = 0;i < c.length;i ++){if(c[i] > max){max = c[i];cnt = 1;a[cnt] = i;}else if(c[i] == max){cnt ++;a[cnt] = i;}}System.out.print(s.substring(0,a[1]));for (int i = 1; i <=cnt; i++) {if(i+1<=cnt)System.out.print(s.substring(a[i],a[i]+1)+str+s.substring(a[i]+1,a[i+1]));else System.out.print(s.substring(a[i],a[i]+1)+str+s.substring(a[i]+1,s.length()));}System.out.println();}}
}
