The lead game, assistance required

Why does this code for the lead game give me a garbage value output. Also i wanted to know if the code is correct

#include

using namespace std;

int main()
{
int m,i,a[20],n,l[10],h,large,j;
cin>>m;
n=m*2;
for(i=0;i<n;i++)
{
cin>>a[i];
}
for(j=0;j<m;j+=2)
{
if(a[j]>a[j+1])
{
cout<<“1”;
l[j]=a[j]-a[j+1];}
else
{cout<<“2”;
l[j]=a[j+1]-a[j];}
}
l[h]=large;

  for(h=0;h<m;h+=2)
  {
     if(l[h+2]>l[h])
        l[h+2]=large;
  }
cout<<large;

return 0;

}

Here you are not storing any value in “int large” …
so some garbage value is there in large when it was declared,and you are printing that value only.

You can overcome this by changing
“l[h+2]=large”
to
“large=l[h+2]”

This approach is not correct …
For the given testcase, your code may work…but it is not correct.

here you are storing the lead values of each round in the array l[].

Those lead values are actually not “a[j]-a[j+1]”…it is actually

the sum of the scores of the player1 upto the "i"th round - the sum of the scores of the player2 till "i"th round…
