{"id": 1766, "question": "Sereja and Dima play a game. The rules of the game are very simple. The players have n cards in a row. Each card contains a number, all numbers on the cards are distinct. There is also one token at each of the two ends of the row, containing the number 5. The players take turns, Sereja moves first. During his turn a player can take one card: either the leftmost card in a row, or the rightmost one. The game ends when there is no more cards. The player who has the maximum sum of numbers on his cards by the end of the game, wins.\n\nSereja and Dima are being greedy. Each of them chooses the card with the larger number during his move. Additionally, each turn Dima tries and fails to cheat by incrementing his sum by 1.\n\nInna is a friend of Sereja and Dima. She knows which strategy the guys are using, so she wants to determine the final score, given the initial state of the game. Help her.\n\n\n-----Input-----\n\nThe first line contains integer n (1 \u2264 n \u2264 1000) \u2014 the number of cards on the table. The second line contains space-separated numbers on the cards from left to right. The numbers on the cards are distinct integers from 1 to 1000.\n\n\n-----Output-----\n\nOn a single line, print two integers. The first number is the number of Sereja's points at the end of the game, the second number is the number of Dima's points at the end of the game.\n\n\n-----Examples-----\nInput\n4\n4 1 2 10\n\nOutput\n12 5\n\nInput\n7\n1 2 3 4 5 6 7\n\nOutput\n16 12\n\n\n\n-----Note-----\n\nIn the first sample Sereja will take cards with numbers 10 and 2, so Sereja's sum is 12.

R2D2 is already working on his rescue, but Luke needs to stay alive as long as possible. For simplicity we will assume that everything happens on a straight line, the presses are initially at coordinates 0 and L, and they move towards each other with speed v_1 and v_2, respectively. Luke has width d and is able to choose any position between the presses. Also, every 0.5 seconds, Luke tries and fails to delay his death by 0.1 seconds by pushing the walls of the rubbish shredder apart. Luke dies as soon as the distance between the presses is less than his width. Your task is to determine for how long Luke can stay alive.\n\n\n-----Input-----\n\nThe first line of the input contains four integers d, L, v_1, v_2 (1 \u2264 d, L, v_1, v_2 \u2264 10 000, d < L)\u00a0\u2014 Luke's width, the initial position of the second press and the speed of the first and second presses, respectively.\n\n\n-----Output-----\n\nPrint a single real value\u00a0\u2014 the maximum period of time Luke can stay alive for.

Consider that all of the offered prices are different.\n\n\n-----Input-----\n\nThe first line of the input contains n (2 \u2264 n \u2264 1000) \u2014 number of bidders. The second line contains n distinct integer numbers p_1, p_2, ... p_{n}, separated by single spaces (1 \u2264 p_{i} \u2264 10000), where p_{i} stands for the price offered by the i-th bidder.\n\n\n-----Output-----\n\nThe single output line should contain two integers: index of the winner and the price he will pay.

440, "question": "Victor tries to write his own text editor, with word correction included. However, the rules of word correction are really strange.\n\nVictor thinks that if a word contains two consecutive vowels, then it's kinda weird and it needs to be replaced. So the word corrector works in such a way: as long as there are two consecutive vowels in the word, it deletes the first vowel in a word such that there is another vowel right before it. If there are no two consecutive vowels in the word, it is considered to be correct.\n\nVictor also thinks consecutive copies of the same letter (for example, \"bb\") are unpleasant.\n\nYou are given a word s. Can you predict what will it become after correction?\n\nIn this problem letters a, e, i, o, u and y are considered to be vowels.\n\n\n-----Input-----\n\nThe first line contains one integer n (1 \u2264 n \u2264 100) \u2014 the number of letters in word s before the correction.\n\nThe second line contains a string s consisting of exactly n lowercase Latin letters \u2014 the word before the correction.\n\n\n-----Output-----\n\nOutput the word s after the correction.\n\n\n-----Examples-----\nInput\n5\nweird\n\nOutput\nwerd\n\nInput\n4\nword\n\nOutput\nword\n\nInput\n5\naaeaa\n\nOutput\na\n\n\n\n-----Note-----\n\nExplanations of the examples: There is

Let's number the problems with integers 1 through m. George estimates the i-th problem's complexity by integer b_{i}.\n\nOf the m problems, each odd-indexed problem (problems 1, 3, 5, ...) is annoying for solvers.\n\nTo make the round good, he needs to put at least n problems there. Besides, he needs to have at least one problem with complexity exactly a_1, at least one with complexity exactly a_2, ..., and at least one with complexity exactly a_{n}. Of course, the round can also have problems with other complexities.\n\nGeorge has a poor imagination. It's easier for him to make some already prepared problem simpler than to come up with a new one and prepare it. George is magnificent at simplifying problems. He can simplify any already prepared problem with complexity c to any positive integer complexity d (c \u2265 d), by changing limits on the input data.\n\nHowever, nothing is so simple. George understood that even if he simplifies some problems, he can run out of problems for a good round. That's why he decided to find out the minimum number of problems he needs to come up with in addition to the m he's prepared in order to make a good round. Note that George can come up with a new problem of any complexity.\n\n\n-----Input-----\n\nThe first line contains two integers n and m (1 \u2264 n, m \u2264 3000) \u2014 the minimal number of problems in a good round and the number of problems George's prepared.

He was upset and decided to postpone his plans of taking over the world, but to become a photographer instead.\n\nAs you may know, the coolest photos are on the film (because you can specify the hashtag #film for such).\n\nBrain took a lot of colourful pictures on colored and black-and-white film. Then he developed and translated it into a digital form. But now, color and black-and-white photos are in one folder, and to sort them, one needs to spend more than one hour!\n\nAs soon as Brain is a photographer not programmer now, he asks you to help him determine for a single photo whether it is colored or black-and-white.\n\nPhoto can be represented as a matrix sized n \u00d7 m, and each element of the matrix stores a symbol indicating corresponding pixel color. There are only 6 colors: 'C' (cyan) 'M' (magenta) 'Y' (yellow) 'W' (white) 'G' (grey) 'B' (black) \n\nThe photo is considered black-and-white if it has only white, black and grey pixels in it. If there are any of cyan, magenta or yellow pixels in the photo then it is considered colored.\n\nTo people who are blue-yellow colorblind, yellow (Y) pixels look grey (G).\n\n-----Input-----\n\nThe first line of the input contains two integers n and m (1 \u2264 n, m \u2264 100)\u00a0\u2014 the number of photo pixel matrix rows and columns respectively.\n\nThen n lines describing matrix rows follow. Each of them contains m space-separated characters describing colors of pixels in a row. Each character in the line is one of the 'C', 'M', 'Y', 'W', 'G' or 'B'.\n\n\n-----Output-----\n\nPrint the \"#Black&White\" (without quotes), if the photo is black-and-white and \"#Color\" (without

"Takahashi, who is a novice in competitive programming, wants to learn M algorithms.\nInitially, his understanding level of each of the M algorithms is 0.\nTakahashi is visiting a bookstore, where he finds N books on algorithms.\nThe i-th book (1\\leq i\\leq N) is sold for C_i yen (the currency of Japan). If he buys and reads it, his understanding level of the j-th algorithm will increase by A_{i,j} for each j (1\\leq j\\leq M).\nHowever, Takahashi getes tired easily, so he can't read more than 3 books a day.\nThere is no other way to increase the understanding levels of the algorithms.\nTakahashi's objective is to make his understanding levels of all the M algorithms X or higher.
