I think we don’t need arrays for this problem. Java solution :-
Scanner sc = new Scanner(System.in);
int T = sc.nextInt();
int cummulativeScorePlayer1 = 0;
int cummulativeScorePlayer2 = 0;
int lead = 0;
int max = Integer.MIN_VALUE;
int playerWon = 0;
while(T-- > 0){
int score1 = sc.nextInt();
int score2 = sc.nextInt();
cummulativeScorePlayer1 = cummulativeScorePlayer1 + score1;
cummulativeScorePlayer2 = cummulativeScorePlayer2 + score2;
if(cummulativeScorePlayer1 > cummulativeScorePlayer2){
lead = cummulativeScorePlayer1 - cummulativeScorePlayer2;
if(lead > max){
max = lead;
playerWon = 1;
}
}
else if(cummulativeScorePlayer2 > cummulativeScorePlayer1){
lead = cummulativeScorePlayer2 - cummulativeScorePlayer1;
if(lead > max){
max = lead;
playerWon = 2;
}
}
}
System.out.println(playerWon+" "+max);can somebody explain whats wrong with my code ?
n=int(input())
a1=[]
b1=[]
g=1
h=2
x=0
y=0
for i in range(n):
a,b= map(int,input().split())
#x,y = map(int, input().split())
a=x+a
b=y+b
if (a>b):
a1.append((a-b))
else:
b1.append((b-a))
x=a
y=b
a1.sort()
b1.sort()
if (a1[-1]>b1[-1]):
print(g,a1[-1])
else:
print([h,b1[-1]])
All code is right and manually giving write answer but during compiling getting error
Plz anyone have a look on my code and help if you can

I have used Array method in c# and most of the test cases are right. CodeChef is saying wrong answer.
I wanna know whats the mistake… let me know…
[CodeChef: Practical coding for everyone](https://My code)
#include
using namespace std;
int main() {
int round,maxi=0,i,n;
cin>>round;
int p1[round],p2[round],result[round],player[round];
for(i=0;i<round;i++)
{
cin>>p1[i]>>p2[i];
if(p1[i]<p2[i]){
result[i]=p2[i]-p1[i];player[i]=2;}
else{
result[i]=p1[i]-p2[i];player[i]=1;}
if(result[i]>maxi){
maxi=result[i];n=player[i];}
}
cout<<n<<" "<<maxi<<endl;
return 0;
}
can anybody help me with this?..why this code is not acceptable
Hi guys ,
can anyone tell me what’s wrong with my code, I gave multiple inputs and all shows correct answer but when I submit is says wrong.
her is my code

thanks in advance
Thank you ssjgz
whats wrong with this solution??
#include<bits/stdc++.h>
using namespace std;
int main(){
// freopen("input.txt", "r", stdin);
int n;
cin>>n;
int a, b ;
int amax=-1 , bmax=-1;
for(int i=0;i<n;i++){
cin>>a>>b;
if( a > b){
amax = max(amax, a-b);
}
else{
bmax = max(bmax, b-a);
}
}
if( amax > bmax){
cout<<1<<" "<<amax<<endl;
}
else{
cout<<2<<" "<<bmax<<endl;
}
return 0;
}
My code is working if I run but not when I submit…
what wrong with this code?
#include<iostream>
int main() {
int t, w=0;
std::cin>>t;
int p1[t], p2[t], total[t], P1CLead, P2CLead;
for (int i=0; i<t;i++){

}
for (int i=0; i<t; i++){

total[i] = p1[i]-p2[i];
if(i==1) P1CLead=total[i];
if(total[i]>P1CLead) P1CLead=total[i];
}

Can anyone show me why this code doesnt work?
#include <bits/stdc++.h>
using namespace std;
int main(){
int i, pone, ptwo, winner, lead;
cin >> i;
int gameRound[i];
for(int a=0; a<i; a++){

if(pone>ptwo) gameRound[a] = ((pone - ptwo) * 10) + 1;
else gameRound[a] = ((ptwo - pone) * 10) + 2;
}
sort(gameRound, gameRound + i);
winner = gameRound[i-1] - ((gameRound[i-1]/10)*10);
lead = gameRound[i-1]/10;
cout << winner << " " << lead;
return 0;
}

@beroul
can you help me
#include
using namespace std;
int main()
{
int t,c=0,d=0,e=0,f=0;

cin >>a>>b;
e = e+a;
f=f+b;
if(a>b)
{
if( (a-b) >c)
{c = (a-b);}
}
else
{
if( (b-a) >d)
{d = (b-a);}
}
}
if(c>d)
{
cout<< “1”<< " "<< (e-f);
}
else
cout<< “2”<< " "<< (f-e);
return 0;
}
i used the same approach but why my code is not accepting. please check it ones and say where i made mistake
