Why it shows error?

#include <bits/stdc++.h>
using namespace std;

int bitonic(int arr[], int n)
{

int inc[n];

int dec[n];
int i, max;

inc[0] = 1;

dec[n-1] = 1;

for (i = 1; i < n; i++)
inc[i] = (arr[i] >= arr[i-1])? inc[i-1] + 1: 1;

for (i = n-2; i >= 0; i--)
dec[i] = (arr[i] >= arr[i+1])? dec[i+1] + 1: 1;

max = inc[0] + dec[0] - 1;
for (i = 1; i < n; i++)
	if (inc[i] + dec[i] - 1 > max)
		max = inc[i] + dec[i] - 1;

return max;

}

int main()
{
int m;
cin>>m;
while(m–){
int n;
cin>>n;
int arr[n];
for(int i=0;i<n;i++){
cin>>arr[i];
}
cout<< bitonic(arr, n);
}
return 0;
}

hello bharat,
your solution is correct.I think some test case is wrong (issue is from our side ).

You need to print newline after every testcase. Is it showing WA or TLE?
