NSTEPS - Number Steps
Starting from point (0,0) on a plane, we have written all non-negative integers 0, 1, 2, ... as shown in the figure. For example, 1, 2, and 3 has been written at points (1,1), (2,0), and (3, 1) respectively and this pattern has continued.
![Illustration](../../../content/steinersp:nsteps.gif)
You are to write a program that reads the coordinates of a point (x, y), and writes the number (if any) that has been written at that point. (x, y) coordinates in the input are in the range 0...10000.
Input
The first line of the input is N, the number of test cases for this problem. In each of the N following lines, there is x, and y representing the coordinates (x, y) of a point.
Output
For each point in the input, write the number written at that point or write No Number if there is none.
Example
Input: 3 4 2 6 6 3 4 Output: 6 12 No Number

Please if anyone can help! My program works for the test cases and any further figures I've tried. I have checked formatting of "No Number". I have the (0,0) case and n<10000 sorted. Still getting WA. Are there any other snags I might have run into, please?? Written in Java with println for outputs and a scanner for inputs. New to this site but was ok with previous tutorial challenges. Last edit: 2015-02-26 20:11:43 |
