Hey everybody. Given an array of n integers, i need to find the product of each of the (n-1) subsets i.e:
ith subset = the product of all the elements except the ith element itself. e.g:
S = {1,0,3,2};
subset_product(1) = 0*3*2=0;
subset_product(2) = 1*3*2=6; etc.
So Any help?

I have the following script which identifies lines in a file which I want to remove, based on an array but does not remove them.
What should I change?
sourcefile = "C:\\Python25\\PC_New.txt"

offending = ["Exception","Integer","RuntimeException"]
def fixup( filename ):
print "fixup ", filename
fin = open( filename )
fout = open( filename2 , "w")
for line in fin.readlines():
for item in offending:
print "got one",line
line = line.replace( item, "MUST DELETE" )
line=line.strip()
fout.write(line)
fin.close()
fout.close()

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!
I'm accessing an array by reference inside a foreach loop, but the unset() function doesn't seem to be working:
foreach ( $this->result['list'] as &$row ) {
if ($this_row_is_boring) {
unset($row);
}
}
print_r($this->result['list']); // Includes rows I thought I unset
Ideas? Thanks!
I am trying to sort an array of strings, but it's not sorting anything.... what am I doing wrong?
string namesS[MAX_NAMES];
int compare (const void * a, const void * b){
return ( *(char*)a - *(char*)b );
}
void sortNames(){
qsort(namesS, MAX_NAMES, sizeof(string), compare);
}
I have a lot of classes and want to create some kind of 'directory'.
So that I can create menus automatically.
Clicking a menu-item would then create an instance of the class and shows the window.
What I want for this is an array of System.Type where I can stuff in all the classes without instantiating them.
Though from my test and (unsuccessful) googling, this doesn't seem possible.
Any ideas?
I want to implement a code that loops inside an array that its size is set by the user that means that the size isn't constant.
for example:
A=[1,2,3,4,5]
then I want the output to be like this:
[1],[2],[3],[4],[5]
[1,2],[1,3],[1,4],[1,5]
[2,3],[2,4],[2,5]
[3,4],[3,5]
[4,5]
[1,2,3],[1,2,4],[1,2,5]
[1,3,4],[1,3,5]
and so on
[1,2,3,4],[1,2,3,5]
[2,3,4,5]
[1,2,3,4,5]
Can you help me implement this code?

question is: there is given array of size n by 2^n(two dimensional) and we should fill it by binary numbers with bits size exactly n or
for example n=5 so result will be

00011
00100
00101
