We are going to explain our hackerrank solutions step by step so there will be no problem to understand the code. For maximum compatibility, this program uses only the basic instruction set (S/360). We will also put comments on every line of code so you can understand the flow of the program. Over the course of the next few (actually many) days, I will be posting the solutions to previous Hacker Rank challenges. Like most of the pattern based programs, this program is simply a code that prints a square chessboard up to N x N size.Here is an output for what we want to print. I rewrote the code 2 times and still same result. For example, an obstacle at location in the diagram above prevents the queen from attacking cells , , and : Given the queen's position and the locations of all the obstacles, find and print the number of squares the queen can attack from her position at . It prints one of the possible solutions … linear dependency e.g. KnightL is a chess piece that moves in an L shape. It should return an integer that describes the number of squares the queen can attack.eval(ez_write_tag([[468,60],'thepoorcoder_com-box-3','ezslot_2',102,'0','0'])); queensAttack has the following parameters: - n: an integer, the number of rows and columns in the board - k: an integer, the number of obstacles on the board - r_q: integer, the row number of the queen's position - c_q: integer, the column number of the queen's position - obstacles: a two dimensional array of integers where each element is an array of integers, the row and column of an obstacle, Input Format.MathJax_SVG_Display {text-align: center; margin: 1em 0em; position: relative; display: block!important; text-indent: 0; max-width: none; max-height: none; min-width: 0; min-height: 0; width: 100%} .MathJax_SVG .MJX-monospace {font-family: monospace} .MathJax_SVG .MJX-sans-serif {font-family: sans-serif} .MathJax_SVG {display: inline; font-style: normal; font-weight: normal; line-height: normal; font-size: 100%; font-size-adjust: none; text-indent: 0; text-align: left; text-transform: none; letter-spacing: normal; word-spacing: normal; word-wrap: normal; white-space: nowrap; float: none; direction: ltr; max-width: none; max-height: none; min-width: 0; min-height: 0; border: 0; padding: 0; margin: 0} .MathJax_SVG * {transition: none; -webkit-transition: none; -moz-transition: none; -ms-transition: none; -o-transition: none} .mjx-svg-href {fill: blue; stroke: blue} .MathJax_SVG_LineBox {display: table!important} .MathJax_SVG_LineBox span {display: table-cell!important; width: 10000em!important; min-width: 0; max-width: none; padding: 0; border: 0; margin: 0}. Two players are playing a game on a chessboard. Equal hackerrank Solution. In each move, a player must move the coin from cell to one of the following locations: Note: The coin must remain inside the confines of the board. Hackerrank - Climbing the Leaderboard Solution Beeze Aal 28.Jun.2020 Alice is playing an arcade game and wants to climb to the top of the leaderboard and wants to track her ranking. A Computer Science portal for geeks. The figure below shows all four possible moves using an board for illustration: Given the initial coordinates of the players' coins, assuming optimal play, determine which player will win the game. It contains well written, well thought and well explained computer science and programming articles, quizzes and practice/competitive programming/company interview Questions. The rules of the game are as follows: The game starts with a single coin located at some coordinates. eval(ez_write_tag([[300,250],'thepoorcoder_com-banner-1','ezslot_7',109,'0','0']));Since there is only one square, and the queen is on it, the queen can move 0 squares. There will always be a valid solution. Hope that helps. I final got the correct solution for all test cases. Its columns are numbered from to , going from left to right. There are attendees, , and .
