This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. when i am using this with sort function it's fine. To review, open the file in an editor that reveals hidden Unicode characters. solution: The key is to query a right end point, make the number that appear on the left of the left, and the other position is set, and the other position is 0, then directly statistics [L, R] interval and the line. Example Input 5 1 1 2 1 3 3 1 5 2 4 3 5 Output 3 2 3 . To review, open the file in an editor that reveals hidden Unicode characters. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. I used MO's algorithm. Let, an array with 8 elements (Like Light OJ), To . waveshare busy timeout. To review, open the file in an editor that reveals hidden Unicode characters. Line 1: n (1 n 30000). SPOJ has a rapidly growing problem set/tasks available for practice 24 hours/day, including many original tasks prepared by the community of expert problem . (Hint1: Use GROUP BY and HAVING. Are you sure you want to create this branch? The meaning: A string of numbers, ask how many different numbers in the [L, R] section. In the next M lines, each line contains two numbers L and R ( 1 <= L <= R <= N ). The second line contains N numbers - the elements of the array, each element is either -1 or 1. If you think your code is simpler than that then we have really different perceptions of what's simple and what's not. 1-sqrt (2)/3/sqrt (S) for _ in xrange (input ()): print '%.6f' % (1 - (2**0.5/3)/ (input ()**0.5)) A Game with Numbers ( NGM) Time: 0.00 Output: Determine who wins at a game which is way more complicated that this solution. Learn more about bidirectional Unicode characters. A tag already exists with the provided branch name. Finding different numbers is to subscript the array to build a chairperson tree. So, Query can be two type. Since numbers are at most one million, you can keep track of how many elements you have in the current window with a simple array count[i]. Learn more about bidirectional Unicode characters . Why I am getting runtime error again and again while same code is working fine in my code editor?

The chairman tree finds the number of different numbers in the interval. And, the other is we can store the queries and return the values as their sequence. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. So, Query can be two type. You can use persistent-segment-tree to solve this task online, or you can remember all queries and solve it offline, using standart segment tree. How can someone possibly think of such a solution unless he has solved a similar problem in past? If the current number has appeared before, then in the current line segment tree, the interval that appeared before is -1, and then the interval . Can anybody tell me why ? No! Learn more about bidirectional Unicode characters. Then first we can find the LCA of the given nodes (a,b) and then find the corresponding values of shortest and longest length edge using a loop from a to LCA and from b to LCA. Here is my code. Easy Longest Increasing Subsequence. Wednesday, 4 October 2017. I solved this task in January. The next line contains an integer K, 1 K 100 000. Let, an array with 8 elements (Like Light OJ). 1 l con c v 2 l con ci. Now, sort it increasingly as their Key but descending with their value. Efficient solution: This problem can be solved by various data structures, like Sqrt decomposition, Sparse table, Segment tree, Fenwick tree, Disjoint set union / Arpa's trick. So, if we mix the original array with the query, is it hardest to recognize which is array and which is query? Tutorial. We will ask you to perfrom some instructions of the following form: CHANGE i ti : change the cost of the i-th edge to ti or QUERY a b : ask for the maximum edge cost on the path from node a to node b Input The first line of input contains an integer t, the number of test cases ( t <= 20). The idea is to keep only the last occurrence of each number in each prefix, Let root[i] be the ith root/segment tree and corresponds to the prefix [0,i], Let the (i+1)th number in original array be X, if it isn't the first occurrence of X, update segment tree and make the number at the index of previous X = (0) and value at current index(i+1) = (1), otherwise just make the value at current index = (1), To answer query [l,r] do range sum query on (r)th root over the same range [l,r], This way each number will be counted only once, and since we are keeping only last occurrence, the answer for any [?,r] is present after processing root[r], In other words, you may reorder the queries by their right end point in ascending order and use a normal segment/bit tree to answer queries offline, The only programming contests Web 2.0 platform, C++ programming tutorial for beginners - part 1. #wrongsubmission #cumulative #sum #query #prefix #sumIn This video we will solve and discuss Spoj problem "Cumulative Sum Query" using Prefix Sum Technique i.
