I used the same code on another editor and it gave me the same output but cant figure out why its giving me error here.
b[i][0]==b[i][1]
This case is not covered.
The way you are calculating sum of digits of numbers is also wrong.
Video Solution:
#include <bits/stdc++.h>
using namespace std;
int compare(long long int a,long long int b){
long long int sum1=0,sum2=0;
while(a>0 && b>0){
sum1+=a%10;
sum2+=b%10;
a=a/10;
b=b/10;
}
if(a){
while(a){
sum1+=a%10;
a=a/10;
}
}
else if(b){
while(b){
sum2+=b%10;
b=b/10;
}
}
if(sum1>sum2) return 10;
else if(sum1<sum2) return 20;
else if(sum1==sum2) return 30;
}
int main() {
long long int t;
cin>>t;
while(t--){
long long int n;
cin>>n;
long long int chef[n];
long long int monty[n];
for(long long int i=0;i<n;i++){
cin>>chef[i];
cin>>monty[i];
}
long long int chefpoints=0;
long long int montypoints=0;
for(long long int i=0;i<n;i++){
int decision=compare(chef[i],monty[i]);
if(decision==10){
chefpoints+=1;
}else if (decision==20){
montypoints+=1;
}else{
montypoints=1;
chefpoints=1;
}
}
if(chefpoints>montypoints){
cout<<"0"<<" "<<chefpoints<<endl;
}else if(chefpoints<montypoints){
cout<<"1"<<" "<<montypoints<<endl;
}else{
cout<<"2"<<" "<<(chefpoints||montypoints)<<endl;
}
}
return 0;
}
//this is my soln why it is giving wrong ans please tell me

If you prefer link
first mistake-
montypoints=1;
chefpoints=1;
second mistake-
chefpoints||montypoints
Notice the changes in code attached above.

Thankyou.
Can anyone point out the mistake in my code, it is giving correct output with the sample cases but not submitting.

can you guys tell me what is wrong here??
Chef and Card Game
Code is in PYTHON 3.6
test_cases = int(input())
for _ in range(test_cases):
rounds = int(input(""))
chef_points = 0
morty_points = 0
for _ in range(rounds):
chef, morty = input().split()
chef_pow = sum(map(int,list(chef)))
morty_pow = sum(map(int,list(morty)))
if chef_pow > morty_pow :
chef_points+=1
elif morty_pow > chef_pow:
morty_points+=1
else:
chef_points+=1
morty_points+=1
if chef_points > morty_points:
print(0,chef_points)
elif chef_points < morty_points:
print(1,morty_points)
else:
print(2,chef_points)
We’d have to guess at the original indentation, and we might get it wrong.
Please format your code yourself - it’s quite easy
