Masala #0729

Sizga \(n (n≥0)\) butun soni berilgan. U mana bu ifodaga teng:

\(n=a_1*b^{k-1}+a_2*b^{k-2}+\dots+a_{k-1}*b+a_k.\)

Bunga misol qilishimiz mumkin,
\(b=17,k=3, a=[11,15,7]\) bo'lsa,
\(n=11*17^2+15*17+7=3179+255+7=3441\).
\(N\) juft yoki toq ekanligini aniqlang.

Birinchi qatorda ikkita butun \(b\) va \(k (2≤b≤100, 1≤k≤105)\).
Ikkinchi qatorda \(a_1,a_2, \dots ,a_k (0≤a_i≤b)\)

Chiqish faylida yagona qatorda, agar \(n\) juft bo'lsa, "even" deb chop eting. Aks holda "odd" deb chop eting.
