how to solve this problem in easy way please tell me…, can somebody please help me with my code here is the link : http://ideone.com/NovXIt, code follows,but not being accepted as solution, #include GitHub statistics: Stars: Forks: Open issues/PRs: View statistics for this project via Libraries.io, or by using our public dataset on Google BigQuery. is it possible? So P has a representation of the length Z + 1 which by definition of F§ means that. } My CodeChef Solution. Our School. CIELRCPT - Editorial. Research The complexity of this approach is O(N / 2K-1 + K2) in the worst test case. Further note that due to (1) C[10]C[9]…C[1]C[0] is a binary representation of R and hence C[0], C[1], …, C[10] are also uniquely determined under the constraints (1). If there are multiple answers satisfying the above conditions, anyone will do. F(P – A1) >= min{F(P - d1), F(P - d2), …, F(P - dK)}. My Code Chef Solutions. days long monthly coding contest and the shorter format Cook-off and Lunchtime coding Write N as Q * 2048 + R, where Q and R are non-negative integers and R < 2048. https://www.codechef.com/viewsolution/14492082, can any one please check my code .I don’t know what is wrong it passed all sample tests. Rating changes for the last round are temporarily rolled back. Codeforces. If there is a score for the problem, this will be … Codeforces. For No > 2048, you have to use rest logic. count=p/2048; CIEL ERP mi-a schimbat complet modul in care imi pot controla business-ul. codechefcli –submit WEICOM /path/to/solution/file C++. int main() Started in 2009, with the aim of improving the problem-solving skills of Indian programmers, CodeChef uses algorithmic contests to help students and professionals test and improve their coding skills. Template for CodeChef. { if(p/2048>1) that’s the answer. AtCoder AGC 050 + CodeChef LTIME91 Post-Contest Discussion We will use dynamic programming. Then A2 + … + AL is some representation of P – A1 of the length L – 1. Then we have, N = C[0] * 1 + C[1] * 2 + C[2] * 4 + … + C[11] * 2048, Note that the total number of summands here is C[0] + C[1] + … + C[10] + C[11].

In this solution he implicitly deals with more natural version of the problem where all powers of two are allowed, that is, we simply need to find bitCount(h). The problem can be solved by greedy algorithm: at each step we should take the largest possible menu that we can. CLI frontend for codechef. That is the answer. size and the likes. Analyzing second implementation of the greedy approach it is easy to see how to make it faster. CodeChef is a competitive programming community, CodeChef uses SPOJ © by Sphere Let B1, …, BZ be the optimal representation for P - dj. count=count+(key-1); We would like to check that you are a human and not a bot. your I found one of the best solution for it, ie: convert decimal to binary and count the number of ones in it. It uses a greedy approach to find the nearest value just smaller than or equal to n from the menu list. Data structure stream #3: New Year Prime Contest 2021 Our tailored focus on academics and the whole child means that every child will find a happy home here. CodeChef was created as a platform to help programmers make it big in the world of algorithms, computer programming and programming contests. Expert advice needed. Positive integer 0 < X <= 2000 – the amount of cash which Pooja wishes to withdraw. Apart from providing a platform for programming Here is where you can show off your computer programming skills. But then P = dj + B1 + … + BZ. scanf("%d",&p); Here is the link to my code : programming contest at the start of the month and two smaller programming challenges at the discussions To get the correct answer he increase answer by 2i-11 instead of 1 for each power of two that is greater than 211 and presented in the binary expansion of h. Greedy Change (Codeforces Beta Round #10, problem E) return 0; License: GNU. The complexity of this method is O(N / 2K-1 + K). Codeforces. Homepage Statistics. Introduction. More than 56 million people use GitHub to discover, fork, and contribute to over 100 million projects. general. count=count_1§; Thus, for optimal representation we should have. Hold right there Sparky!! R = C[0] * 1 + C[1] * 2 + C[2] * 4 + … + C[10] * 1024 <= 1 + 2 + 4 + … + 1024 = 2047 < 2048. which means by one of the definition of floor function that C[11] = floor(N / 2048) = Q. Leave a comment if you have any doubts. Programming competitions and contests, programming community. At CodeChef, we work hard to … ctd++; Ideone is something more than a pastebin; it's an online compiler and debugging tool which allows to compile and run code online in more than 40 programming languages. Programming competitions and contests, programming community. Now let’s see why greedy approach produces the same solution. Since A1 is equal to one of dj then Labs. Use our practice section to better prepare yourself for the multiple Thus we obtain third implementation of the greedy algorithm with complexity O(K). Write N as Q * 2048 + R, where Q and R are non-negative integers and R < 2048. { or Our programming Programming competitions and contests, programming community. My solution is a bit different and is very short if you are using C++ and stl as your tool to solve the problem Clearly F(0) = 0. This is because at first N / 2K-1 steps we have only one iteration of inner loop (we break at 2048) and then we have at most K steps for each of which we have at most K steps in the inner loop. end of the month. First one is simple but slower in general. to help else printf("\n"); middle and We’ve currently received your request for data information. Try your hand at one of our many practice problems and submit your solution in the language } Preparing for coding contests were never this much fun! If R = 2h[1] + 2h[2] + … + 2h[K] is a binary representation of R then the optimal representation of N is N = 2048 + … + 2048 + 2h[1] + 2h[2] + … + 2h[K] where we have Q copies of 2048. Ciel biedt diverse softwareoplossingen op het gebied van facturatie, voorraadbeheer, BTW-aangiften en budgetbeheer- en optimalisatie. – the amount of cash which Pooja wishes to withdraw it is easy to see how to make faster.
