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++){
std::cin>>p1[i]>>p2[i];
}
for (int i=0; i<t; i++){
if (p1[i]>p2[i]) {
total[i] = p1[i]-p2[i];
if(i==1) P1CLead=total[i];
if(total[i]>P1CLead) P1CLead=total[i];
}
if (p2[i]>p1[i]) {
total[i] = p2[i]-p1[i];
if(i==1) P2CLead=total[i];
if(total[i]>P2CLead) P2CLead=total[i];
}
}
if(P1CLead>P2CLead) {
std::cout<<1<<" "<<P1CLead;
}
if(P2CLead>P2CLead) {
std::cout<<2<<" "<<P2CLead;
}
}

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++){
cin >> pone >> ptwo;
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;
}
See my post directly above yours
@beroul
can you help me
#include
using namespace std;
int main()
{
int t,c=0,d=0,e=0,f=0;
cin >>t;
for(int i=0;i<t;i++)
{
int a,b;
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

I also used the same approach but why my code is not acception. please check my code and explaination where I made mistake.

you are finding the lead for individual rounds…you have to add scores of each round and then find the overall lead, so basically your lead array is incorrect.
Here is my cpp code if it helps:
#include <bits/stdc++.h>
using namespace std;
int main() {
int n,i,max,min,sum1=0,sum2=0;
cin >> n;
int p1[n],p2[n],lead[n];
for (i=0;i<n;i++){
cin >> p1[i];
cin >> p2[i];
}
for(i=0;i<n;i++){
sum1= sum1+p1[i];
sum2= sum2+p2[i];
lead[i]=sum1-sum2;
}
max = lead[0];
for (i = 0; i < n; i++)
{
if (max < lead[i])
max = lead[i];
}
min = lead[0];
for (i = 0; i < n; i++)
{
if (min > lead[i])
min = lead[i];
}
min = -min;
if (max>min){
cout << "1 " << max;
}
if (max<min){
cout << "2 " << min;
}
return 0;
}
What’s wrong with my solution…
#include
using namespace std;
int main()
{
int i=0,l=0,w=0;
cin >> i;
while (i–)
{
int a,b,k=0;
cin>>a>>b;
if(a>b)
{
k = a-b;
}
else
{
k = b-a;
}
if(l <= k)
{
l = k;
if(a>b) w=1;
else w = 2;
}
}
cout<<w<<" "<<l;
return 0;
}
Please Check my code:
T = int(input())
Z = list()
for i in range(T):
X,Y = [int(i) for i in input().split()]
Z.append(X-Y)
if max(Z) > abs(min(Z)):
print(1,max(Z))
else:
print(2,abs(min(Z)))
Give me a suggestion What is wrong with this code>
cumu_score = []
lead = 0
for _ in range(int(input())):
p1,p2 =map(int,input().split())
diff = abs(p1 - p2)
if p1 > p2 :
cumu_score.append((1,diff))
else:
cumu_score.append((2,diff))
cumu_score.sort(key = lambda x: x[1])
w = cumu_score[len(cumu_score) - 1][0]
l = cumu_score[len(cumu_score) - 1][1]
print(w,l)
