I think could shown in video is wrong

#1

// Online C++ compiler to run C++ program online
#include
#include <bits/stdc++.h>
using namespace std;

int solve(vector coins,int amount,int dp[]){
if(amount==0) return 0;

int mini=INT_MAX;
if(dp[amount]!=0){
    return dp[amount];
}
for(int i=0;i<coins.size();i++){
    if(amount>=coins[i]){
        int subprob=solve(coins,amount-coins[i],dp);
        mini=min(mini,subprob+1);
    }
}

dp[amount]=mini;
return dp[amount];

}

int main() {
int n, amount;
cin >> n >> amount;

vector<int> coins(n);
for(int i=0;i<n;i++){
    cin >> coins[i];
}

int dp[100]={0};
dp[0]=0;
cout << solve(coins,amount,dp);
return 0;

}

that’s my code same as shown in video but its not working for the test case: amount=9 , coins[3,4,5]
