340 - Master-Mind Hints

We can only learn by making mistakes! The more irritating the mistake is, the more we have learned...

Could you please remove the essential parts of the code in your previous post? It's a spoiler now.

Why WA?

#include <stdio.h>
const int MAX = 1001;
int gameno,i,j,n;
int code[MAX],guess[MAX],match[MAX];
int strong,weak;

int main(void)
{
gameno = 0;
while(scanf("%d",&n),n!=0)
{
for(i=0;i<n;i++)
scanf("%d",&code[i]);
printf("Game %d:\n", ++gameno);
while(1)
{
for(i=0;i<n;i++)
scanf("%d",&guess[i]);
if (!guess[0]) break;
for(i=0;i<n;i++)
if (guess[i] == code[i]) match[i] = 1; // strong match
else match[i] = 0; // empty
for(i=0;i<n;i++)
if (!match[i])
for(j=0;j<n;j++)
if (!match[j] && (code[i] == guess[j])) match[i] = 2; // weak match
strong = weak = 0;
for(i=0;i<n;i++)
{
if (match[i] == 1) strong++;
if (match[i] == 2) weak++;
}
printf(" (%d,%d)\n",strong,weak);
}
}
return 0;
}

I can't understand why I got a compile error, this is my code:

import java.io.IOException;
import java.util.StringTokenizer;

/**

* @author Gabriel Rivera Safadi
*/
class Main {

static String readLine() {
int car = -1;
String s = "";
try {
while (true) {
car = System.in.read();
if (car == '\n' || car < 0)
break;
if (car != 13)
s = s + (char)car;
}
} catch (IOException e) {
return null;
}
if (s.length() == 0)
return null;
return s;
}

static boolean ceros(int v[], int n) {
int cont = 0;
for (int i = 0; i < n; i++) {
if (v == 0)
cont++;
}
if (cont == n)
return true;
return false;
}

/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
String s;
int game = 1;
while (!(s = readLine()).equals("0")) {
System.out.println("Game "+game+":");
game++;
int n = Integer.parseInt(s);
int v[] = new int[n];
StringTokenizer st = new StringTokenizer(readLine());
for (int i = 0; i < n; i++)
v = Integer.parseInt(st.nextToken());
int w[] = new int[n];
while (true) {
int v2[] = new int[n];
for (int i = 0; i < n; i++)
v2 = v;
st = new StringTokenizer(readLine());
for (int i = 0; i < n; i++)
w = Integer.parseInt(st.nextToken());
if (ceros(w,n))
break;
int c1 = 0;
int c2 = 0;
for (int i = 0; i < n; i++) {
if (v2 == w) {
v2 = 0;
w = 0;
c1++;
}
}
for (int i = 0; i < n; i++) {
for (int j = 0; j < n && v2 != 0; j++) {
if (v2[i] == w[j] && i != j) {
v2[i] = 0;
w[j] = 0;
c2++;
}
}
}
System.out.println(" ("+c1+","+c2+")");
}
}
}

}


Somebody please help me.

I have no idea why I am getting WA
it passes all the I/O given in the board but still WA
please someone check
here is the code:

Code: Select all

Removed after AC

pls help

[shiplu_1320]

just change

Code: Select all

if(secret[i]=='#' && guess[i]=='#')continue;

to

Code: Select all

if(secret[i]=='#' && guess[j]=='#')continue;

Good luck

[abid_iut]

Thanks a lot
it was a silly mistake
anyway got AC
thanks

[sazzadcsedu]

whats wrong with my code.
WA.

#include<stdio.h>

int main()

{
int sec[10]; // secret code
int gue[10]; //guess code
int temp[10];
int n,strmatch,wkmatch;
int i,zero;
int j,counter=1;;



//freopen("input.txt","r",stdin);
// freopen("output.txt","w",stdout);




while(scanf("%d",&n)==1)
{

if(n==0)
break;

for(i=0;i<n;i++)

{
scanf("%d",&sec);
}

printf("Game %d:\n",counter);

while(1)


{


for(i=0;i<n;i++)

{

temp=sec;

}

strmatch=0;
wkmatch=0;
zero=0;

for(j=0;j<n;j++)
{

scanf("%d",&gue[j]);

if(gue[j]==0)

zero=zero+1;

}

if(zero==n)
break;


for(i=0;i<n;i++)
{
if(gue==temp)
{
strmatch=strmatch+1;
gue=-10;
temp=-100;
}
}


printf(" (%d,",strmatch);


for(i=0;i<n;i++)

{
for(j=0;j<n;j++)

{
if(gue==temp[j])
{
//printf("i;%d j:%d\n",i,j);
wkmatch=wkmatch+1;
temp[j]=-50;
break;
}
}
}

printf("%d)\n",wkmatch);

}

counter++;
}

return 0;

1 3 5 5
5 5 6 6
0 0 0 0
0

Can anybody please explain the sample output clearly? I didn't understand how to determine i and j for each guess.
For each guess for the given sample input in problem, explain me how each match(i, j) in output is generated.
