我的代码工作正常并显示最大出现字符的数量但不显示最大字符。还告诉我编写代码的聪明方法我是初学者

  let notificationMessage = "Beacon button clicked"
  let notification = UILocalNotification()
  notification.alertBody = notificationMessage
  notification.alertAction = "OK"
  UIApplication.shared.presentLocalNotificationNow(notification)

}

Answer 1

你只需要一个额外的

.model small
.stack 100h
.data
    msg1 db " <-- Non alpha!$"
msg2 db "Bye!$"

.code

start:
            ; display ?
mov dl, "?"         ; copy ? to dl
mov ah, 2h      ; display subprogram
int 21h         ; display ?

mov dl, " "         ; Provide space
mov ah, 2h      ; display subprogram
int 21h         

            ; read character from keyboard
mov ah, 1h      ; keyboard input subprogram
int 21h         ; read character into al 
            ; save character while we display a Return and Line-feed
    cmp al,65d      ; 'A'
    jb Non_alpha
    cmp al,90d      ; 'Z'
    ja above_alpha_upper

    mov bl, al              ; save character in bl
    add bl,32d      ; ADD 32 decimal
mov dl, bl      ; copy character to dl
mov ah, 2h      ; display subprogram
int 21h         ; display character in dl
    jmp x

Non_alpha:
    mov ax, @data
    mov ds,ax
    mov dx,offset msg1
    mov ah,9h
    int 21h
    jmp x           ; je,ja, jb

 above_alpha_upper:
cmp al,97d      ; 'a'
jb Non_alpha
cmp al,122d     ; 'z'
ja Non_alpha

mov bl, al              ; save character in bl
    sub bl,32d      ; SUBTRACT 32 decimal
mov dl, bl      ; copy character to dl
mov ah, 2h      ; display subprogram
int 21h         ; display character in dl

x:              ; exit
mov dl, 13d             ; dl = CR, Dh
    mov ah, 2h              ; display subprogram
    int 21h                 ; display CR
            ; display Line-feed
    mov dl, 10d             ; dl = LF , Ah
    mov ah, 2h              ; display subprogram
    int 21h                 ; display LF
            ; display character read from keyboard

mov ax, @data
    mov ds,ax
    mov dx, offset msg2 ; Bye
    mov ah,9h
    int 21h

mov ax, 4c00h       ; return to ms-dos
int 21h
end start

Answer 2

只需更改将字符保存到

的行

    max_occ = (char) i;

索引是字符的代码，asc中的值是该字符的计数。

你的代码的变量名有点难以理解，也许好一点（恕我直言）：

final int MAX = 255;

int[] count = new int[MAX];
char maxChar = ...
int maxCount = -1;

按照惯例，

和变量以小写，类和接口名称开头，大写......

Answer 3

你可以在同一个第一个循环中捕获它

for (int i=0; i<n; i++)
  if (++asc[Chars[i]] > max_occ) {
    ++max_occ;
    max_char = Chars[i];
  }

使用哈希表的最大出现字符
