CF1144B Parity Alternated Deletions
Description
Polycarp has an array $ a $ consisting of $ n $ integers.
He wants to play a game with this array. The game consists of several moves. On the first move he chooses any element and deletes it (after the first move the array contains $ n-1 $ elements). For each of the next moves he chooses any element with the only restriction: its parity should differ from the parity of the element deleted on the previous move. In other words, he alternates parities (even-odd-even-odd-... or odd-even-odd-even-...) of the removed elements. Polycarp stops if he can't make a move.
Formally:
- If it is the first move, he chooses any element and deletes it;
- If it is the second or any next move:
- if the last deleted element was odd, Polycarp chooses any even element and deletes it;
- if the last deleted element was even, Polycarp chooses any odd element and deletes it.
- If after some move Polycarp cannot make a move, the game ends.
Polycarp's goal is to minimize the sum of non-deleted elements of the array after end of the game. If Polycarp can delete the whole array, then the sum of non-deleted elements is zero.
Help Polycarp find this value.
Input Format
The first line of the input contains one integer $ n $ ( $ 1 \le n \le 2000 $ ) — the number of elements of $ a $ .
The second line of the input contains $ n $ integers $ a_1, a_2, \dots, a_n $ ( $ 0 \le a_i \le 10^6 $ ), where $ a_i $ is the $ i $ -th element of $ a $ .
Output Format
Print one integer — the minimum possible sum of non-deleted elements of the array after end of the game.
