java - Queen Collision -


i solving queen collision problem can located here

i need understanding instructions. understand reading file, don't understand how know queen positions are?

i don't understand part:

the first line of dataset contains blank separated positive integers n g, n indicates n x n board size, , g number of linear patterns of queens described, n < 30000, , g < 250. next g lines each contain 5 blank separated integers, k x y s t, representing linear pattern of k queens @ locations (x + i*s, y +i*t), = 0, 1, ..., k-1. value of k positive. if k 1, values of s , t irrelevant, , given 0. queen positions on board. total number of queen positions among linear patterns no more n, , these queen positions distinct.

the first line of dataset contains blank separated positive integers n g, n indicates n x n board size, , g number of linear patterns of queens described, n < 30000, , g < 250. the next g lines each contain 5 blank separated integers, k x y s t, representing linear pattern of k queens @ locations (x + i*s, y +i*t), = 0, 1, ..., k-1. value of k positive. if k 1, values of s , t irrelevant, , given 0. queen positions on board. total number of queen positions among linear patterns no more n, , these queen positions distinct.

you read g on first line, , tells how many more lines there are. on each of lines, read k, x, y, s , t, , use position queens. k tells how many queens position set, x , y tell position first one, , s , t tell distance between queens. don't see how there's difficult understand this.

i'm using abcpdf , i'm curious if can recursively call addimageurl() function assemble pdf document compile multiple urls? something like: int pagecount = 0; int theid = thedoc.addimageurl("http://stackoverflow.com/search?q=abcpdf+footer+page+x+out+of+", true, 0, true); //assemble document while (thedoc.chainable(theid)) { thedoc.page = thedoc.addpage(); theid = thedoc.addimagetochain(theid); } pagecount = thedoc.pagecount; console.writeline("1 document page count:" + pagecount); //flatten document (int = 1; <= pagecount; i++) { thedoc.pagenumber = i; thedoc.flatten(); } //now try again theid = thedoc.addimageurl("http://stackoverflow.com/questions/1980890/pdf-report-generation", true, 0, true); //assemble document while (thedoc.chainable(theid)) { thedoc.page = thedoc.addpage(); theid = thedoc.addimagetoc...
