I iterate through the sales data array and check if there exists any consecutive pair of years where the sales decrease. If I find such a pair, I have tried modifying one of the elements to make the sales increase. If there are more than one such pairs or if modifying any of the elements does not result in increasing sales, then it is not possible to present the annual sales graph as required

CAN SOMEONE CORRECT IT import java.io.; import java.math.; import java.text.; import java.util.; import java.util.regex.*;

public class Solution {

public static void main(String[] args){
    Scanner sc = new Scanner(System.in);
    int t=sc.nextInt();
    while(t>0)
    {
        int n=sc.nextInt();
        int a[]=new int[n];
        for(int i=0;i<n;i++)
        {
            a[i]=sc.nextInt();

        }
        if(n==1)
        {
            System.out.println("YES");
        }
        else
        {
        int l=0,c=0;
        for(int i=0;i<n-1;i++)
        {
            if(a[i]>a[i+1])
            {
                l++;
            }
            else
            {
             c++;
            }
        }
        if(l==0||l==1)
        {
           System.out.println("YES");
        }
        if(l>1)
        {
            System.out.println("NO");
        }
        }
        t--;
    }
        }

}

my code code worked for many custom test cases . suggestions if any is appreciated

include

using namespace std; int main(){ int row,count1=0,max1=0; cin>>row; vector> myvector(row); for(int i=0;i>col; myvector[i]=vector (col); for(int j=0;j>myvector[i][j]; }

}
for(int i=0;i<myvector.size();i++){
    for(int j=0;j<myvector[i].size()-1;j++){
        if(myvector[i][j]>myvector[i][j+1] || myvector[i][j+1]<max1 ){
            max1=myvector[i][j];
            count1++;
        }
    }
    if(count1>1)
    cout<<"NO\n";
else
    cout<<"YES\n";
}

}

hi anyone post the solution in java..
