import java.io.*;
public class Main
{
static void logInput(String[] log,int n) throws IOException
{
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
int a=0,b=0;
for (int i = 0; i < n; i++)
{
String s = br.readLine();
if (log[0]==null)
{
a++;
log[0] = s;
}
else if (log[0].equals(s))
a++;
else if (log[1]==null)
{
b++;
log[1] = s;
}
else if (log[1].equals(s))
b++;
}
if (a>b)
System.out.println(log[0]);
else if (a<b)
System.out.println(log[1]);
else if(a==b)
System.out.println("Draw");
}
static void testCase() throws IOException
{
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
int n = Integer.parseInt(br.readLine());
String[] log = new String[2];
logInput(log,n);
}
public static void main(String[] args) throws IOException
{
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
int t = Integer.parseInt(br.readLine());
for (int i = 0; i < t; i++)
{
testCase();
}
br.close();
}
}
and I get a nzec now if I combine all the function i.e do everything in main() I get correct ans
import java.io.*;
public class Main
{
public static void main(String[] args) throws IOException
{
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
int t = Integer.parseInt(br.readLine());
for (int i = 0; i < t; i++)
{
int n = Integer.parseInt(br.readLine());
String[] log = new String[2];
int a=0,b=0;
for (int k = 0; k < n; k++)
{
String s = br.readLine();
if (log[0]==null)
{
a++;
log[0] = s;
}
else if (log[0].equals(s))
a++;
else if (log[1]==null)
{
b++;
log[1] = s;
}
else if (log[1].equals(s))
b++;
}
if (a>b)
System.out.println(log[0]);
else if (a<b)
System.out.println(log[1]);
else if(a==b)
System.out.println("Draw");
}
br.close();
}
}
I don’t understand how dividing it into functions can cause a nzec do I need to catch the exceptions thrown by other methods except main()?
My code works on online IDE but is not getting accepted and saying it’s NZEC error in Python
¿Can anybody tell me why?
n1=int(input().strip())
for i in range(n1):
arr=[]
n2 = int(input().strip())
for j in range(n2):
arr_t = str(input().strip())
arr.append(arr_t)
arr_uniq=list(set(arr))
if (arr.count(arr_uniq[0])>arr.count(arr_uniq[1])):
print(arr_uniq[0])
elif (arr.count(arr_uniq[0])<arr.count(arr_uniq[1])):
print(arr_uniq[1])
else:
print("Draw")
I am getting WA in here. the code works fine with no error. Help is appreciated !!.
i request codechef team to give data for different test case which is input for our submission.
here’s my code
N = 0 can also be present, in that case while loop runs will give you tle, as it runs for 2*INT_MAX iterations, after which it loops back to 0 and breaks.
Input files are large and cin/cout are the slowest input/output streams. So, use the lines “ios_base::sync_with_stdio(false);” in your code. See editorialist submission for details.
okay I found the solution there was a memory leak which happens due to multiple buffer reader objects sharing the same input stream so I declared a static field like
static BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
Hello, my python code is working for custom input case but is not getting accepted and showing “Wrong Answer”.Can anyone tell me my mistake, please?
Thanks in advance!

Can someone provide me test case that fails, seems to be working all the time
It’s not getting accepting I am getting Wrong Answer, also the problem needs to be clear with n = 0 as inout the output should be draw. It could have been clear when no teams are given as the question says there are atleast two teams, highly contradicting.
#include
using namespace std;
int main(){
int testcases;
cin >> testcases;
while(testcases>0){
int numofentries,firstteamwins=0,secondteamwins=0;
cin >> numofentries;
string firstteam;
string secondteam;
string answer;
if(numofentries>0){
cin >> firstteam;
firstteamwins++;
for(int i=0;i<numofentries-1;i++){
string winstring;
cin>> winstring;
if(winstring==firstteam){
firstteamwins++;
}
else{
secondteam=winstring;
secondteamwins++;
}
}
if(firstteamwins>secondteamwins){
answer=firstteam;
}
else if(secondteamwins>firstteamwins){
answer=secondteam;
}
else if(secondteamwins==firstteamwins){
answer=“Draw”;
}
cout << answer<<"\n";
}
else{
cout << “Draw”<<"\n";
}
testcases–;
}
return 0;
}
This is my approach.
It should be clarified what should be the output in case of n=0.
Caused me lots of wa on this question.
