Alice, Bob and Chocolate

 2000ms  65536K

描述：

Alice and Bob like games. And now they are ready to start a new game. They have placed n chocolate bars in a line. Alice starts to eat chocolate bars one by one from left to right, and Bob — from right to left. For each chocololate bar the time, needed for the player to consume it, is known (Alice and Bob eat them with equal speed). When the player consumes a chocolate bar, he immediately starts with another. It is not allowed to eat two chocolate bars at the same time, to leave the bar unfinished and to make pauses. If both players start to eat the same bar simultaneously, Bob leaves it to Alice as a true gentleman.

How many bars each of the players will consume?

译文：爱丽丝和鲍勃喜欢游戏。现在他们准备开始一个新的游戏。他们已经把n个巧克力棒排成一行。爱丽丝从左边向右边一个接一个的吃巧克力棒，鲍勃从右边向左边。对于每个巧克力棒，玩家吃掉它所需要的时间是已知的(爱丽丝和鲍勃以相同的速度吃掉它们)。当一个玩家开始吃，另一个也立刻开始。不允许同时吃两个巧克力棒，不许半途而废，也不允许停顿。如果两个玩家开始吃同一根巧克力棒，鲍勃作为绅士将让给爱丽丝。

输入：

The first line contains one integer n (1 ≤ n ≤ 105) — the amount of bars on the table. The second line contains a sequence t1, t2, ..., tn (1 ≤ ti ≤ 1000), where ti is the time (in seconds) needed to consume the i-th bar (in the order from left to right).

译文：第一行包含一个整数 n (1 ≤ n ≤ 105) —桌子上巧克力棒的数量。第二行包含一串序列t1, t2, ..., tn (1 ≤ ti ≤ 1000),ti是需要吃第i个巧克力棒（按从左向右的顺序）花的时间（按秒算）。

输出：

Print two numbers a and b, where a is the amount of bars consumed by Alice, and b is the amount of bars consumed by Bob.
