I submitted a dp solution to problem 996A of Hit The Lottery. I didnt find any error in my code and logic seems to be fine. Can someone tell me why am I getting this error. I am new to CP and would appreciate if the nuances are clearly highlighted to me.
#include<bits/stdc++.h>
using namespace std;
#define min(a,b) ((a<=b)?a:b)
typedef long long ll;
int main()
{
vector<long long int> v1 = {1, 5, 10, 20, 100};
long long int n;
cin>>n;
vector<long long int> dp(n+1,0);
dp[0] = 1;
long long int min;
for(int i = 1;i<=n;i++)
{
min = dp[i - 1] + 1;
for(auto j:v1)
{
if(j<=i&&(dp[i - j]+dp[j]<min))
{
min = dp[i - j] + dp[j];
}
}
dp[i] = min;
}
cout<<dp[n];
return 0;
}
