here is one puzzle..for those who have heard about it might seem very simple....
Suppose k is an integer, you have to count the numbers of 1's in the binary representation of number k. Use as less number of iterations as u can....
Just an hint, it could be done in a less than statements with out any loop.

Hi Dholey,
In your given example, you loop will iterate by total number of bits in the given data type.
for example of a 'int' it will iterate 32 times on a 32 or 64 bit operating system.
In my example, i will interate only total number of '1' in the given number...
For any bit, the probablity of being '1' or '0' is just half, so the complexity of your algorithm is just double of mine.

I dont know how to do it in less than a statement.... but
this will also work...
int n = 34; // number for which we have to find total '1', u can change it
int i = 0;
do {
++i;
while(n=(n&(n-1));
cout

Yes. I am interested.
Well I am working on one now..It is related to graphics.Herez the description:
I need to plot a graph (a 2-D)using hexadecimal(ex:0x5A) values on Y axis against some integers on the X axis . The plotting must happen continuously with screen refreshing it self every 5 seconds.(This would look like an oscilloscope refreshing).
Assume the hexadecimal values are available continuously.

is it your problem and you want some type of help? If yes then please let me know the equation by which u will use your x and y values to draw the graph. if the quardratic equation is 1:1 then ....
suppose,
your data is like
int x-axis[] = {a, b, c, d, e}; // some integer value
int y-axis[] = {f, g, h, i, j}; // some hexadecimal value
now u can draw your graph like....
int i = 0;
while (i

is it not possible that we create a seprate group on mylot for this type of discussion only and intrested people can join it and participate init on regular basis?
As i m new to mylot, i do not know too much about it. I think you must a lot of friends which must be intrested to join such a group. we can grow if we take such a step. What do u think?
