I have a singleton class, and I will compile it as a library static(lib) or dynamic(dll).
Is it guaranteed that calls to same file in a machine always refer to same and unique instance in both cases?
Hi,
I have a function that will get a JSON array with objects. In the function I will be able to loop through the array, access a property and use that property. Like this:
Variable that I will pass to the function will look like this:
[{"id":28,"Title":"Sweden"}, {"id":56,"Title":"USA"}, {"id":89,"Title":"England"}]
function test(myJSON)
{
// maybe parse my the JSON variable?
// and then I want to loop through it and access my IDs and my titles
}
Any suggestions how I can solve it?
Regards,
Fredrik
I was looking for something over the web when I came across this question. Have no idea of how to solve it. Help me out please.
Suppose we have an array
a1,a2,... ,an, b1,b2,..., bn
How to change this array to
a1,b1,a2,b2, ..., an,bn in O(n) time and in O(1) space.
Hey guys I have an assigned array from mysql results and I simply want to number them starting at one. Does anyone know how to do this?
while ($row=mysql_fetch_assoc($query)){

Hello,
I'm curious, whether there is any way to print formated numpy.arrays, e.g., in the way similar to this:
x = 1.23456
print '%.3f' % x
If I want to print the numpy.array of floats, it prints several decimals, often in 'scientific' format, which is rather hard to read even for low-dimensional arrays. However, numpy.array apparently has to be printed as a string, i.e., with %s. Is there any solution ready for this purpose? Many thanks in advance :-)
Dynamic programming is, almost by definition, to find a shortest/longest path on an implicit dag.
Every DP algorithm just does this.
An Holographic algorithm can be loosely described as something that counts perfect matchings in implicit planar graphs.
So, my question is: are there any other families of algorithms that use well-known algorithms over implicit graphs to achieve a considerable speedup?
I have this set
NSMutableSet *mySet = [NSMutableSet setWithObjects: @"2", @"8", @"7", @"0", @"3", nil];
I copy the set to an array and sort it using
NSArray *sortedArray = [[mySet allObjects] sortedArrayUsingSelector:@selector(compare:)];
The resulting array is in exactly the same order as the set and is not being sorted. Why?
thanks for any help.
EDIT: CORRECING A TYPO.
Hi,
I have a list/array and need to process certain elements, but also need the index of the element in the processing.
Example:
List Names = john, mary, john, bob, simon
Names.Where(s = s != "mary").Foreach(MyObject.setInfo(s.index, "blah")
But cannot use the "index" property with lists, inversely if the names were in an Array I cannot use Foreach...
Any suggestions?
Hello friends,
I am a newbie in Fortran.
Can any1 tell me how to define an integer array in prior.
E.g.
I want to define an array with no.of days in 12 months.
like...
integer,allocatable(12,1) :: days
days=[31,28,31,30,31,30,31,31,30,31,30,31]
Is this syntax correct? If not, please let me know the correct one.
Thanks
Praveen
I think this might be a pretty simple question, but I haven't been able to figure it out yet. If I've got a 2-dimensional array like so:
int[,] = new int[2,3] { {1, 2, 3}, {4, 5, 6} };
What's the best way to iterate through each dimension of the array with a nested foreach statement?
Hello!
I would like to store only .txt filenames from a specific dir (let's say: /sdcard/docs/) into an String array.
Example:
In /sdcard/docs/ there are 5 files: 'foo.txt', 'bar.jpg', 'foofoo.txt', 'loool.png' and 'foobar.txt'. I would like to get array with contents: "foo.txt", "foofoo.txt", "foobar.txt"
How could I do it? Thanks =)
hi guys
i had an array of objects , i need to know how should i sort my unsorted array in descending order according to the highest value inside objects
i need this using for loops not the easy way.
i had done this but it seems there is a problem
code
student[] temp=new student[s.length];
for (int i=0;i s[i + 1].GetGpa())
{
temp[i] = s[i];
}
}
how should i do it using for loops
Does anyone know do there have any way that I can encrypt the array in php??
for example:
$arr_value = array("1","2","3","4");
any way that I can encrypt $arr_value, also decrypt it later ini php?
I have a JSON array that looks like this:
['Monkey','Cheetah','Elephant','Lizard','Spider']
I also have a text input. I want to test whether the value of the input upon 'blur' is also in the array and if it is do something.
Knowing a bit of python I tried something like this:
var existing_animals = ['Monkey','Cheetah','Elephant','Lizard','Spider']
$('input').blur(function() {
user_animal = $(this).val()
if (user_animal in existing_animals) {
alert('Animal already exists!')
}
});
So, how rookie is my mistake?
Array(0= blabla
1 = blabla
2 = blblll) etc..
Is there a way to change all the numeric keys to "Name" without looping through the array (so a php function)?
What are the advantages of using
var foo = [];
over using
var bar = new Array();
i've been told to use [] over new Array() but never with much explanation
Hi. I've been thinking about a program logic, but I cannot draw a conclusion to my problem.
Here, I've implemented stack and queue operations to a fixed array.
int A[1000];
int size=1000;
int top;
int front;
int rear;
bool StackIsEmpty()
{
return (top==0);
}
bool StackPush( int x )
{
if ( top >= size ) return false;
A[top++] = x;
return true;
}
int StackTop( )
{
return A[top-1];
}
bool StackPop()
{
if ( top <= 0 ) return false;
A[--top] = 0;
return true;
}
bool QueueIsEmpty()
{
return (front==rear);
}
bool QueuePush( int x )
{
if ( rear >= size ) return false;
A[rear++] = x;
return true;
}
int QueueFront( )
{
return A[front];
}
bool QueuePop()
{
if ( front >= rear ) return false;
A[front++] = 0;
return true;
}
It is presumed(or obvious) that the bottom of the stack and the front of the queue is pointing at the same location, and vice versa(top of the stack points the same location as rear of the queue).
For example, integer 1 and 2 is inside an array in order of writing. And if I call StackPop(), the integer 2 will be popped out, and if I call QueuePop(), the integer 1 will be popped out.
My problem is that I don't know what happens if I do both stack and queue operations on the same array. The example above is easy to work out, because there are only two values involved. But what if there are more than 2 values involved?
For example, if I call
StackPush(1);
QueuePush(2);
QueuePush(4);
StackPop();
StackPush(5);
QueuePop();
what values will be returned in the order of bottom(front) from the final array?
I know that if I code a program, I would receive a quick answer. But the reason I'm asking this is because I want to hear a logical explanations from a human being, not a computer.

Hi guys,
let's assume I've got the address of my array (passed as a pointer to the function) in esi register. How can I access a particular cell of the array? i.e:
my_array[a + b * c]
where c is constant.
Thank you for the fast reply!
