## Problem: Vedant and his Hidden Array CodeChef Solution

Vedant has a hidden array of NN elements. Given the bitwise AND of all elements of the array, determine whether the total sum of the elements is odd, even or cannot be determined.

#### Input Format

• The first line of each input contains TT – the number of test cases. The test cases then follow.
• The only line of each test case contains two space-separated integers NN and AA – the number of elements in the hidden array and the bitwise AND of all the elements in the hidden array.

#### Output Format

For each test case, output `Even` if the sum of all elements in the hidden array is even, `Odd` if the sum of all elements in the hidden array is odd, or `Impossible` if the parity cannot be determined.

Note: You may print each character of the string in uppercase or lowercase (for example, the strings `eVen``EvEn``even` and `EVEN` will all be treated as identical).

#### Constraints
