Not able to figure out error

#1

#include
using namespace std;

int main()
{
int T;
cin>>T;

if(T>=1 && T<=100){
for (int TestCase = 0; TestCase < T; TestCase++)
{

int N,max;
cin>>N;

int Array[N];
int Inc[N] ={0};
int Dec[N] ={0};
Inc[0]=1;
Dec[N-1]=1;

for (int i = 0; i < N; i++)
{
    cin>>Array[i];
}

for (int i = 1; i < N; i++)
{
    if (Array[i]>Array[i-1])
    {
        Inc[i]= Inc[i-1]+1;
    }
    else
    {
        Inc[i]=1;
    } 
}

for (int i = N-2; i >=0; i--)
{
    if (Array[i]>Array[i+1])

        Dec[i]= Dec[i+1]+1;
    }
    else
    {
        Inc[i]=1;
    } 
}
max =Inc[0]+Dec[0]-1;

for (int i = 0; i <N; i++)
{
    if (Inc[i]+Dec[i]-1>max)
    {
        max=Inc[i]+Dec[i]-1;
    }
    
}
cout<<max<<endl;
}
}

}

#2

(Array[i] >= Array[i-1]) here

(Array[i] >= Array[i+1]) here

Rest looks good
If this resolves your query then please hit a like :slight_smile:

#3

not able to find error in this

#4

if consecutive elements are same then also we can say its increasing or decreasing
Say
1 1 1
So here increasing array should be
1 2 3 instead of
1 1 1
Similarly for decreasing array

#5

I did it but there is also some which is not figure out…

This one should be dec[i]=1

thanks … .
