void main(){
	unsigned t,n,first,next,most,temp,i,j,sum[50];
	bool flag;
	cin>>t;
	for(i=0;i<t;i++){
		cin>>n>>first;
		most=temp=1,flag=false;
		for(j=0;j<n-1;j++){
			cin>>next;
			if (flag) {
				if (first<next) {
					temp++;
					flag = !flag;
				}else{
					temp=1;
					flag = false;
				}
			}else{
				if (first>next) {
					temp++;
					flag=!flag;
				}else{
					temp=1;
					flag = false;
				}
			}
			if (most<temp) {
				most = temp;
			}
			first = next;
		}
		sum[i]=most;
	}
	for(i=0;i<t;i++)
		cout<<sum[i]<<endl;
