Algorithm for sorting an array using another array named gaps[] -


this piece of code program. code tends sort array horses size n. how array gap in sorting array horses? 

int gaps[]={701,301,132,57,23,10,4,1}; (k = 0; k < 8; k++) (i = gaps[k]; < n; ++i)  { temp = horses[i]; (j = i; j >= gaps[k] && horses[j-gaps[k]] > temp; j -= gaps[k]) horses[j] = horses[j-gaps[k]]; horses[j] = temp; }

gaps[] experimentally derived sequence shell sort. take @ last entry in wiki table shell sort:

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
