Given an array **A** of **N** integers, Your task is to complete the function **find3Numbers** which finds any 3 elements in it such that A[i] < A[j] < A[k] and i < j < k. You need to return them as a vector, if no such element is present then return the empty vector of size 0.

**Input:**

The first line of input contains an integer T denoting the no of test cases. Then T test cases follow. The first line of each test case contains an integer N denoting the size of the array A in the next line are N space separated values of the array A.

**Output:**

For each test case in a new line output will be 1 if the sub-sequence returned by the function is present in array A else 0.

**Constraints:**

1 <= T <= 100

1 <= N <= 10^{5}

1 <= A[ ] <= 10^{6}

**Example:
Input:**

2

5

1 2 1 1 3

3

1 1 3

1

0

There are 2 test cases

a sub-sequence 1 2 3 exist
