Dhruba Mitra has been cheated by his Girlfriend recently and so his mental situation is not so good. He doesn\u0027t come home, stays in RAPL and solves problem all day long. As Nobel vai didn\u0027t know anything about that secret, he asked Dhruba to play FIFA (game) with him . But Dhruba didn\u0027t agree and gave Nobel vai a list of integers , and asked the summation of them. \n\u003cbr/\u003e\nThank God, I was present there. I knew everything about the situation. Actually, after getting \" ছ্যাঁকা \", Dhruba hates all couples . Not only that, he also hates the number \"2\" and all the numbers that is divided by 2. So if Nobel vai tells him a summation that is divided by 2 he would be very upset. ( I know it\u0027s weird, but its true ) . As Nobel vai is our বড়ভাই he doesn\u0027t want Dhruba to be upset . So if the real summation is even, he (Nobel vai) will erase some numbers ( one or more) from the list to make the sum odd. But he also will try to make the sum as large as possible, so that Dhruba doesn\u0027t doubt his calculation.If he can\u0027t make an odd sum in any way ,he will erase all the numbers and answer 0(as there is no other way). Now , Nobel vai wants to play Fifa. So, he needs someone to help him doing this calculation. Would you help him ?"}},{"title":"Input","value":{"format":"HTML","content":"The first line contains an integer n (1 ≤ n ≤ 100), which is the number of integers in the list.
