# DCP-382: Prime and Even-Odd Back to All Problems

Easy Beginners Problems > Ad-hoc

>A prime number is a natural number greater than **1** that has no positive divisors other than 1 and itself. First few prime numbers are: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29 ........... Your task is to find whether the summation of **N-th** and **M-th** prime number is even or odd.<br> For example , If the input is **2** and **4** then the **2nd** and **4th** prime number are **3** and **7**, and sum is **3 + 7 = 10** .Here 10 is **Even**. So, the answer is **Even**.<br>if input is 1 and 2 then the prime number are **2** and **3**,so **2 + 3 = 5** which is **Odd** Input: ------ There are several test case and **input will be terminated by end of file**.***Total number of test cases will not exceed 50***.<br> Each case contains two integers **N and M(1 ≤ N , M ≤ 10^18)** as described above. Output: ------- For each test case, print either **"Even”** (without quotes) or **“Odd”** (without quotes). If the summation of the **N-th** and **M-th** prime numbers is even then print **“Even”**, otherwise print **“Odd”** Sample Input ------------ 1 2 2 3 Sample Output ------------- Odd Even
