Is there an easier way than below to find the longest item in an array?
arr = [
[0,1,2],
[0,1,2,3],
[0,1,2,3,4],
[0,1,2,3]
]
longest_row = []
@rows.each { |row| longest_row = row if row.length > longest_row.length }
p longest_row # => [0,1,2,3,4]
I've something like this
Object[] myObjects = ...(initialized in some way)...
int[] elemToRemove = new int[]{3,4,6,8,...}
What's the most efficient way of removing the elements of index position 3,4,6,8... from myObjects ?
I'd like to implement an efficient Utility method with a signature like
public Object[] removeElements(Object[] object, int[] elementsToRemove) {...}
The Object[] that is returned should be a new Object of size myObjects.length - elemToRemove.length
I have a class like this
class someclass{
public function somemethod(){}
}
Now I have an array:
$somearray['someclass'] = new someclass();
$somearray['somemethod'] = 'somemethod';
How can I fire them, I tried the following:
$somearray['someclass']->$somearray['somemethod']();
usign this I get the following error:
Fatal error: Method name must be a string in ......................
Anyone have an idea on how to do this?
This may be a bit of an easy, headesk sort of question, but my first attempt surprisingly completely failed to work. I wanted to take an array of primitive longs and turn it into a list, which I attempted to do like this:
long[] input = someAPI.getSomeLongs();
List<Long> = Arrays.asList(input); //Total failure to even compile!
What's the right way to do this?
I have a string representing bits, such as:
"0000101000010000"
I want to convert it to get an array of bytes such as:
{0x0A, 0x10}
The number of bytes is variable but there will always be padding to form 8 bits per byte (so 1010 becomes 000010101).
Is it possible to initialise an array in Java using the 'advanced' for loop?
e.g.
Integer[ ] numbers = new Integer[20];
int counter = 0;
for ( Integer i : numbers )
{
i = counter++;
}
for ( Integer i : numbers )
{
System.out.println(i);
}
This prints all nulls, why is that?
I am new to jScript and have written this code [which works perfectly]. Its purpose is to test that the term for the amount of loan is not exceeded. Can the process be consolidated into one array where you pass the loan amount which returns the term based on the range i.e. 6000 to 7000 = 96
function TestMaxTerm()
{
var LnAmt = 14000 //Testing Purposes
var Term = 0 //Testing Purposes
if (LnAmt > 0 && LnAmt <= 1000){Term = 0;}
if (LnAmt > 1000 && LnAmt <= 2000){Term = 1;}
if (LnAmt > 2000 && LnAmt <= 3000){Term = 2;}
if (LnAmt > 3000 && LnAmt <= 4000){Term = 3;}
if (LnAmt > 4000 && LnAmt <= 5000){Term = 4;}
if (LnAmt > 5000 && LnAmt <= 6000){Term = 5;}
if (LnAmt > 6000 && LnAmt <= 7000){Term = 6;}
if (LnAmt > 7000 && LnAmt <= 8000){Term = 7;}
if (LnAmt > 8000 && LnAmt <= 9000){Term = 8;}
if (LnAmt > 9000 && LnAmt <= 10000){Term = 9;}
if (LnAmt > 10000 && LnAmt <= 11000){Term = 10;}
if (LnAmt > 11000 && LnAmt <= 12000){Term = 11;}
if (LnAmt > 11000){Term = 12;}
//Obtain Maximum Term for Loan Amount
var MaxTerm = new Array();
MaxTerm[0] = 24; MaxTerm[1]=36; MaxTerm[2] = 48; MaxTerm[3] = 60;
MaxTerm[5] = 72; MaxTerm[5]=84; MaxTerm[6] = 96; MaxTerm[7] = 108;
MaxTerm[8] = 120; MaxTerm[9]=132; MaxTerm[10] = 164; MaxTerm[11] = 176;
MaxTerm[12] = 420;
var text = MaxTerm[Term];
alert(text);
}
I have a file saved as UTF-8, and i'm reading it like this:
ReadFile(hFile, pContents, pFile->nFileSize, &dwRead, NULL);
(pContents is a BYTE* of size nFileSize)
its just a small file with 100 bytes or so, contains text which i want to read into memory in wchar_t* format, so i can set the text of edit and static controls with the unicode text.
How can i convert the bytes to UTF-8?
edit (i don't want to use fstream or wfstream)
I am having difficulty for using array model binding.
Actually I can see that the values sent from the views are not binded to the model and the arrays still have the values already instantiated. How can I solve this problem?
I have a dynamic array of strings, the elements of which I would like to localize. Is there a way to localize the strings without iteration e.g. something like using "makeObjectsPerformSelector". Thank you
I've got code that takes a PIL image and converts it to a ctypes array to pass out to a C function:
w_px, h_px = img.size
pixels = struct.unpack('%dI'%(w_px*h_px), img.convert('RGBA').tostring())
pixels_array = (ctypes.c_int * len(pixels))(*pixels)
But I'm dealing with big images, and unpacking that many items into function arguments seems to be noticeably slow. What's the simplest thing I can do to get a reasonable speedup?
I'm only converting to a tuple as an intermediate step, so if it's unnecessary, all the better.
I need a big null array in C as a global. Is there any way to do this besides typing out
char ZEROARRAY[1024] = {0, 0, 0, /* ... 1021 more times... */ };
?
How can I convert a Class to byte array in C#. This is a managed one so the following code is failing
int objsize = System.Runtime.InteropServices.Marshal.SizeOf(objTimeSeries3D);
byte[] arr = new byte[objsize];
IntPtr buff = System.Runtime.InteropServices.Marshal.AllocHGlobal(objsize);
System.Runtime.InteropServices.Marshal.StructureToPtr(objTimeSeries3D, buff, true);
System.Runtime.InteropServices.Marshal.Copy(buff, arr, 0, objsize);
System.Runtime.InteropServices.Marshal.FreeHGlobal(buff);
Thanks
Very similar to this post
How can I declare template array as a parameter in templated function?
Something like this code:
template <unsigned i> void my_func (char (&a)[i]); //yes, I do need that reference
If I have an array named $myArray how can I get a reference to it from a string of the same name myArray. I tried:
eval('myArray');
But that gave me an error.
I am trying to fumble through python, and learn the best way to do things. I have a string where I am doing a compare with another string to see if there is a match:
if paid[j].find(d)>=0:
#BLAH BLAH
If 'd' were an array, what is the most efficient way to see if the string contained in paid[j] has a match to any value in 'd'?
hi friends,
How to read XML file into two dimensional array using java. Am new to this concept. Please suggest me any ideas and suggest any websites and examples regarding this question.
Hi folks.
I have a array like this:
my @arr = ("Field3","Field1","Field2","Field5","Field4");
Now i use map like below , where /DOSOMETHING/ is the answer am seeking.
my %hash = map {$_ => **/DOSOMETHING/** } @arr
Now I require the hash to look like below:
Field3 = 0
Field1 = 1
Field2 = 2
Field5 = 3
Field4 = 4
Any help?
Hi how should i iterate array of variables and reassign value to each variable. E.g in jQuery
function test(param1, param2) {
$.each([param1, param2], function (i, v) {
//check if all the input params have value, else assign the default value to it
if (!v)
v = default_value; //this is wrong, can't use v, which is value
}
}
How should I get the variable and assign new value in the loop?
Thank you very much!
What is the smartest way of searching through an array of strings for a matching string in Perl?
One caveat, I would like the search to be case-insensitive
so "aAa" would be in ("aaa","bbb")
