#include <stdio.h>
int Count_Digit(const int N
, const int D
);

{

, D
;
scanf("%d %d", &N
, &D

C++版
#include<iostream>
using namespace std
;
int Count_Digit(const int N
, const int D
);
int main()
{
int N
, D
;
cin
>> N
>> D
;
cout
<<Count_Digit(N
, D
);
return 0;
}
int Count_Digit(const int N
, const int D
) {
int n
= N
;
int number
[10];
int size
= 0;
int count
= 0;
for (int i
= 0; i
< 10; i
++)
{
number
[i
] = n
% 10;
n
= n
/ 10;
size
++;
if (n
== 0) {
break;
}
}
for (int j
= 0; j
< size
; j
++) {
if ((D
+ number
[j
] == 0) || (D
- number
[j
] == 0)) {
count
++;
}
}
return count
;
}
Java版
public class Main{
private static int Count_Digit(final int N
, final int D
) {
int n
= N
;
int [] number
= new int[10];
int size
= 0;
int count
= 0;
for (int i
= 0; i
< 10; i
++)
{
number
[i
] = n
% 10;
n
= n
/ 10;
size
++;
if (n
== 0) {
break;
}
}
for (int j
= 0; j
< size
; j
++) {
if ((D
+ number
[j
] == 0) || (D
- number
[j
] == 0)) {
count
++;
}
}
return count
;
}
public static void main(String
[] args
) {
int N
=0,D
=0;
Scanner scanner
= new Scanner(System
.in
);
if(scanner
.hasNext()) {
N
= scanner
.nextInt();
D
= scanner
.nextInt();
}
scanner
.close();
System
.out
.println(Count_Digit(N
, D
));
}
}
