algorithm - Prime factors using recursion in Java -

i'm having trouble recursion in java. have following method , should transform recursion without loop. public static list<integer> primesloop(int n) { list<integer> factors = new arraylist<integer>(); int f = 2; while (f <= n) if (n % f == 0) { factors.add(f); n /= f; } else f++; return factors; } the recursive method should start same form: public static list<integer> primesrec(int n); and should define methods transformation result example: primesrec(900) -> prime factors of 900 : [2, 2, 3, 3, 5, 5] you can add f argument overloading, , adding private method take it, , invoked "main" public method. in private method, have 3 cases: stop clause: n==1: create new empty list n%f == 0: recurse n'=n/f, f'=f, , add f list. n%f != 0: recurse n'=n, f'=f+1, don't add list. code: public static list<integer> primesrecursive...

Perl - Changing Excel Worksheet name -

in perl script writing, trying find way open existing excel spreadsheet, change name of first worksheet, , save it. seem simple task haven't found simple way it. spreadsheet::writeexcel can change worksheet name, seems can't read in existing excel file. another constraint perl module use shouldn't need installation. can work around if there's no option, make things more complicated. edit: using activeperl 5.18, modules included in ideal. the way of doing while preserving else in excel file use win32::ole . that requires having excel installed on computer on program run, and, of course, works on windows. if can't that, have read excel file, , write out contents file, changing name of worksheet in process. depending on have in source excel file, can rather involved rather fast. see " how can merge 2 excel (xls) files in perl or batch?

java - Why is there a transformation of hashcode to get the hash and is it a good idea for all keys? -

this question has answer here: understanding strange java hash function 6 answers i see implementation of hashmap applies kind of transformation hashcode actual hash. 1 please me understand how transformation works and additionally if make difference if object store integer? as taken javadoc of method hash(object) in openjdk java 8 hashmap implementation (assuming jvm concerned about): /** * computes key.hashcode() , spreads (xors) higher bits of hash * lower. because table uses power-of-two masking, sets of * hashes vary in bits above current mask * collide.

f# - FunScript querySelector null result -

i want use document.queryselector method html node. in js can receive null result. in f# result type element , it's neither nullable nor optional , it's not clear how check null . how can handle situation when queryselector doesn't match dom node? yes, it's true f# code assumes element not nullable. can trick compiler think otherwise in several ways. easiest 1 box value this: let el = globals.document.queryselector(".myclass") if (box el) = null dosomething() else dosomethingelse()` box ignored when generating js code, there's no performance penalty in doing this.

c - Incrementing pointer to static allocated array -

by how pointer incremented in these situations , why? void f(int a[]) { a++; printf("%d", *a); } void g(int a[][m]) { a++; printf("%d", *a[0]); } lets in main have static allocated array n elements , static allocated matrix ( 2d array ) n rows , m columns , i'm calling functions f , g ( i couldn't write in code because unable post question lot of code , no text ). in both cases pointers incremented once.:) a++; their values changed sizeof of types of objects point to. value of first pointer changed sizeof( int ) , value of second pointer changed sizeof( int[m] ) take account parameter int a[][m] adjusted int ( *a )[m] thus within functions both pointers point second elements of arrays. two-dimensional array element one-dimensional array. , statement printf("%d", *a[0]); will output first element (integer) of second "row" of two-dimensional array.

git - How to determine closest divergent branch-point -

not sure how word question. imagine it's been asked on so pointer existing post great. complexity: linear in number of commits, not number of named refs. ideally concise sequence of git commands instead of manual loops. let's have following commit graph: a b | / | /-- c |/ a & b named refs start with. less abstract concepts, origin/master & b name of branch conceptually based on a. finding commits made b diverge trivial & natively supported via ... notation. i'm, however, looking find if there's named ref c happens on path a...b . should not find c in either of graphs below assuming d named ref & c not. a b d | / / | /-- c |/ b | / | /-- c |/ \ d | / | / ---- edit: in example assuming both c & d named refs, expect find d: a b | /-- d | /-- c |/ | | in other words, commit closest b head of branch. in example, d & b different refs same commit, should not find d & instead find c: a b,...
