Can anyone tell me why it is giving WA. Thanks.

#include <iostream>
using namespace std;
int *a;
int main() {
int n,t,count=1;
scanf("%d",&t);
while(t--)
{
    scanf("%d",&n);
    a=new int[n];
    count=1;
 for(int i=0;i<n;i++)
     scanf("%d",&a[i]);
 
        for(int i=1;i<n;i++)
        {
            if(a[i]<a[i-1]){
            count++;
 
            }
        }
        printf("%d\n",count);
    }
	return 0;
}
