There are n walruses standing in a queue in an airport. They are numbered starting from the queue's tail: the 1-st walrus stands at the end of the queue and the n-th walrus stands at the beginning of the queue. The i-th walrus has the age equal to ai.The i-th walrus becomes displeased if there's a younger walrus standing in front of him, that is, if exists such j (i < j), that ai > aj. The displeasure of the i-th walrus is equal to the number of walruses between him and the furthest walrus ahead of him, which is younger than the i-th one. That is, the further that young walrus stands from him, the stronger the displeasure is.The airport manager asked you to count for each of n walruses in the queue his displeasure.
Print n numbers: if the i-th walrus is pleased with everything, print "-1" (without the quotes). Otherwise, print the i-th walrus's displeasure: the number of other walruses that stand between him and the furthest from him younger walrus.

The i-th walrus has the age equal to ai.The i-th walrus becomes displeased if there's a younger walrus standing in front of him, that is, if exists such j (i &lt; j), that ai &gt; aj. The displeasure of the i-th walrus is equal to the number of walruses between him and the furthest walrus ahead of him, which is younger than the i-th one. That is, the further that young walrus stands from him, the stronger the displeasure is.The airport manager asked you to count for each of n walruses in the queue his displeasure.
Print n numbers: if the i-th walrus is pleased with everything, print "-1" (without the quotes). Otherwise, print the i-th walrus's displeasure: the number of other walruses that stand between him and the furthest from him younger walrus.

There are n walruses standing in a queue in an airport. They are numbered starting from the queue's tail: the 1-st walrus stands at the end of the queue and the n-th walrus stands at the beginning of the queue. The i-th walrus has the age equal to ai.The i-th walrus becomes displeased if there's a younger walrus standing in front of him, that is, if exists such j (i &lt; j), that ai &gt; aj. The displeasure of the i-th walrus is equal to the number of walruses between him and the furthest walrus ahead of him, which is younger than the i-th one. That is, the further that young walrus stands from him, the stronger the displeasure is.The airport manager asked you to count for each of n walruses in the queue his displeasure.
Print n numbers: if the i-th walrus is pleased with everything, print "-1" (without the quotes). Otherwise, print the i-th walrus's displeasure: the number of other walruses that stand between him and the furthest from him younger walrus.

Ziota found a video game called "Monster Invaders".Similar to every other shooting RPG game, "Monster Invaders" involves killing monsters and bosses with guns.For the sake of simplicity, we only consider two different types of monsters and three different types of guns.Namely, the two types of monsters are: a normal monster with $$$1$$$ hp. a boss with $$$2$$$ hp. And the three types of guns are: Pistol, deals $$$1$$$ hp in damage to one monster, $$$r_1$$$ reloading time Laser gun, deals $$$1$$$ hp in damage to all the monsters in the current level (including the boss), $$$r_2$$$ reloading time AWP, instantly kills any monster, $$$r_3$$$ reloading time The guns are initially not loaded, and the Ziota can only reload 1 gun at a time.The levels of the game can be considered as an array $$$a_1, a_2, \ldots, a_n$$$, in which the $$$i$$$-th stage has $$$a_i$$$ normal monsters and 1 boss. Due to the nature of the game, Ziota cannot use the Pistol (the first type of gun) or AWP (the third type of gun) to shoot the boss before killing all of the $$$a_i$$$ normal monsters.If Ziota damages the boss but does not kill it immediately, he is forced to move out of the current level to an arbitrary adjacent level (adjacent levels of level $$$i$$$ $$$(1 &lt; i &lt; n)$$$ are levels $$$i - 1$$$ and $$$i + 1$$$, the only adjacent level of level $$$1$$$ is level $$$2$$$, the only adjacent level of level $$$n$$$ is level $$$n - 1$$$). Ziota can also choose to move to an adjacent level at any time. Each move between adjacent levels are managed by portals with $$$d$$$ teleportation time.In order not to disrupt the space-time continuum within the game, it is strictly forbidden to reload or shoot monsters during teleportation. Ziota starts the game at level 1. The objective of the game is rather simple, to kill all the bosses in all the levels. He is curious about the minimum time to finish the game (assuming it takes no time to shoot the monsters with a loaded gun and Ziota has infinite ammo on all the three guns). Please help him find this value.
Print one integer, the minimum time to finish the game.

Initially there are no boxes on the stack.Okabe, being a control freak, gives Daru 2n commands: n of which are to add a box to the top of the stack, and n of which are to remove a box from the top of the stack and throw it in the trash. Okabe wants Daru to throw away the boxes in the order from 1 to n. Of course, this means that it might be impossible for Daru to perform some of Okabe's remove commands, because the required box is not on the top of the stack.That's why Daru can decide to wait until Okabe looks away and then reorder the boxes in the stack in any way he wants. He can do it at any point of time between Okabe's commands, but he can't add or remove boxes while he does it.Tell Daru the minimum number of times he needs to reorder the boxes so that he can successfully complete all of Okabe's commands.

He can do it at any point of time between Okabe's commands, but he can't add or remove boxes while he does it.Tell Daru the minimum number of times he needs to reorder the boxes so that he can successfully complete all of Okabe's commands. It is guaranteed that every box is added before it is required to be removed.
Print the minimum number of times Daru needs to reorder the boxes to successfully complete all of Okabe's commands.

The heat during the last few days has been really intense. Scientists from all over the Berland study how the temperatures and weather change, and they claim that this summer is abnormally hot. But any scientific claim sounds a lot more reasonable if there are some numbers involved, so they have decided to actually calculate some value which would represent how high the temperatures are.Mathematicians of Berland State University came up with a special heat intensity value. This value is calculated as follows:Suppose we want to analyze the segment of $$$n$$$ consecutive days. We have measured the temperatures during these $$$n$$$ days; the temperature during $$$i$$$-th day equals $$$a_i$$$.We denote the average temperature of a segment of some consecutive days as the arithmetic mean of the temperature measures during this segment of days. So, if we want to analyze the average temperature from day $$$x$$$ to day $$$y$$$, we calculate it as $$$\frac{\sum \limits_{i = x}^{y} a_i}{y - x + 1}$$$ (note that division is performed without any rounding). The heat intensity value is the maximum of average temperatures over all segments of not less than $$$k$$$ consecutive days. For example, if analyzing the measures $$$[3, 4, 1, 2]$$$ and $$$k = 3$$$, we are interested in segments $$$[3, 4, 1]$$$, $$$[4, 1, 2]$$$ and $$$[3, 4, 1, 2]$$$ (we want to find the maximum value of average temperature over these segments).You have been hired by Berland State University to write a program that would compute the heat intensity value of a given period of days.

The heat during the last few days has been really intense. Scientists from all over the Berland study how the temperatures and weather change, and they claim that this summer is abnormally hot. But any scientific claim sounds a lot more reasonable if there are some numbers involved, so they have decided to actually calculate some value which would represent how high the temperatures are.Mathematicians of Berland State University came up with a special heat intensity value. This value is calculated as follows:Suppose we want to analyze the segment of $$$n$$$ consecutive days. We have measured the temperatures during these $$$n$$$ days; the temperature during $$$i$$$-th day equals $$$a_i$$$.We denote the average temperature of a segment of some consecutive days as the arithmetic mean of the temperature measures during this segment of days. So, if we want to analyze the average temperature from day $$$x$$$ to day $$$y$$$, we calculate it as $$$\frac{\sum \limits_{i = x}^{y} a_i}{y - x + 1}$$$ (note that division is performed without any rounding). The heat intensity value is the maximum of average temperatures over all segments of not less than $$$k$$$ consecutive days. For example, if analyzing the measures $$$[3, 4, 1, 2]$$$ and $$$k = 3$$$, we are interested in segments $$$[3, 4, 1]$$$, $$$[4, 1, 2]$$$ and $$$[3, 4, 1, 2]$$$ (we want to find the maximum value of average temperature over these segments).You have been hired by Berland State University to write a program that would compute the heat intensity value of a given period of days. Are you up to this task?
Print one real number — the heat intensity value, i. e., the maximum of average temperatures over all segments of not less than $$$k$$$ consecutive days. Your answer will be considered correct if the following condition holds: $$$|res - res_0| &lt; 10^{-6}$$$, where $$$res$$$ is your answer, and $$$res_0$$$ is the answer given by the jury's solution.
