Hello, in this problem 1011 — Marriage Ceremoniesthe priority index is not clear to me. I used bottom up manner and calculate the max adjacent values. Like-

for me the values are 8 6 2 total 16.But the submission gets wa. In udebug one test case is-

5
5 10 10 2 3
2 11 3 10 10
16 12 1 5 2
4 2 11 5 2
1 8 14 4 13

Ans:60.Which for me 14 11 12 11 10 total 58.What am I missing here? Need help with that.

My code

#include<bits/stdc++.h>
using namespace std;
#define ll long long
const int N=2e6+5,mod=1e9+7;

int mat[20][20],dp[20][20];
int main()
{
	int t,cnt=1;cin>>t;
	while(t--)
	{
		int n;cin>>n;
		for(int i=1;i<=n;++i)
		{
			for(int j=1;j<=n;++j)
			{
				cin>>mat[i][j];
			}
		}
		memset(dp,0,sizeof(dp));
		for(int i=1;i<=n;++i)
		{
			for(int j=1;j<=n;++j)
			{
				if(n&1)
				{
					if(j==(n+1)/2)
					{
						int temp=max(max(dp[i-1][j],dp[i-1][j-1]),dp[i-1][j+1]);
						dp[i][j]=max(dp[i][j],temp)+mat[i][j];
					}
					else if(j<(n+1)/2)
					{
						dp[i][j]=max(max(dp[i][j],dp[i-1][j]),dp[i-1][j+1])+mat[i][j];
					}
					else
					{
						dp[i][j]=max(max(dp[i][j],dp[i-1][j]),dp[i-1][j-1])+mat[i][j];
					}
				}
				else
				{
					if(j<=n/2)
					{
						dp[i][j]=max(max(dp[i][j],dp[i-1][j]),dp[i-1][j+1])+mat[i][j];
					}
					else
					{
						dp[i][j]=max(max(dp[i][j],dp[i-1][j]),dp[i-1][j-1])+mat[i][j];
					}
				}
			}
		}
		//cout<<endl;
		int ma=0;
		for(int i=1;i<=n;++i)
		{
			for(int j=1;j<=n;++j)
			{
				//cout<<dp[i][j]<<" ";
				ma=max(ma,dp[i][j]);
			}
			//cout<<endl;
		}
		cout<<"Case "<<cnt++<<": "<<ma<<endl;
	}
	return 0;
}
