Sep 22, 2016 · However, this may not give you the optimal solution. Consider the case n = 60. Your code finds the following answer: 60 -> 10 -> 5 -> 4 -> 2 -> 1 -> 0 (length 7 chain) Note that it chose 10 from (6,10). The optimal solution is: 60 -> 12 -> 4 -> 2 -> 1 -> 0 (length 6 chain) To find this solution, you must consider other factors such as 12 from ...
May 21, 2021 · To explore all solution tree and find globally optimal solution, we must choose the best result both from all possible divisor pairs and from solution(n-1) My weird translation to Java uses bottom-up dynamic programming to make execution faster. We calculate solutions for values i from 1 to n, they are written into table[i].
Nov 28, 2019 · The queen is standing at position (r_q, c_q). In a single move, she can attack any square in any of the eight directions (left, right, up, down, and the four diagonals). There are obstacles on the chessboard, each preventing the queen from attacking any square beyond it on that path. Given the queen's position and the locations of all the ...
Jan 19, 2022 · I'm not sure if this would be the approach for the function rep_one. Since this problem is under dynamic programming, I'm not even sure if it can be solved without storing past values. I've edited my question to include a solution posted on the discussion section of the problem. \$\endgroup\$ –
Nov 1, 2022 · You will be given a square chess board with one queen and a number of obstacles placed on it. Determine how many squares the queen can attack. Please find below my implementation. Its working fine ...
Jan 31, 2017 · 4 4 4 4. Sample Output 0. 9 9. Explanation 0. The queen is standing at position (4, 4) (4, 4) on a 4 4 x 4 4 chessboard with no obstacles: We then print the number of squares she can attack from that position, which is 9 9. My introduction of algorithm: This algorithm is a medium one in hackerrank world codesprint 9 contest, and I like to code ...
The key is to iterate every item in the first row, and from it go down the diagonal. Then iterate every item in the last column (without the first, which we stepped through in the previous step) and then go down its diagonal. Here is source code that assumes the matrix is a square matrix (untested, translated from working python code):
Jan 31, 2018 · In this problem we are asked: Given a set, S, of n distinct integers, print the size of a maximal subset, S', of where the sum of any two numbers in it is not evenly divisible by k. Code My idea...
Jun 22, 2021 · I mean, in 1 possibility solution of 2 is different from 2nd possibility because in first one I've to traverse 4->3->2 here solution of 2 is 2 and in 2nd possibility we traverse 4->2 and solution of 2 here is 1 now these 2 same sub-problems have different values because of the solving from top to bottom. Now I'm totally confused here.
May 21, 2020 · I'm solving Queen's Attack II problem in Hackerrank. My idea is traverse through every obstacles to find the closest obstacle in each directions (left, right, up down and 4 diagons. My function only passed half of testcases. Then I search on the Internet and I found a similar solution but different in code structure, obsiously it passed all ...
