You are given an integer \(n\) (\(n \ge 0\)) represented with \(k\) digits in base (radix) \(b\). So,$$$\(n = a_1 \cdot b^{k-1} + a_2 \cdot b^{k-2} + \ldots a_{k-1} \cdot b + a_k.\)\(For example, if \)b=17, k=3\( and \)a=[11, 15, 7]\( then \)n=11\cdot17^2+15\cdot17+7=3179+255+7=3441\(.Determine whether \)n$$$ is even or odd.
The first line contains two integers \(b\) and \(k\) (\(2\le b\le 100\), \(1\le k\le 10^5\)) — the base of the number and the number of digits.The second line contains \(k\) integers \(a_1, a_2, \ldots, a_k\) (\(0\le a_i < b\)) — the digits of \(n\).The representation of \(n\) contains no unnecessary leading zero. That is, \(a_1\) can be equal to \(0\) only if \(k = 1\).
Print ""even"" if \(n\) is even, otherwise print ""odd"".You can print each letter in any case (upper or lower).
In the first example, \(n = 3 \cdot 13^2 + 2 \cdot 13 + 7 = 540\), which is even.In the second example, \(n = 123456789\) is odd.In the third example, \(n = 32 \cdot 99^4 + 92 \cdot 99^3 + 85 \cdot 99^2 + 74 \cdot 99 + 4 = 3164015155\) is odd.In the fourth example \(n = 2\).
