2 | 3 //Output is 3 7 | 9 //Output is 15  I tried 2 | 3 in the console and I got an output of 3. When I did 7 | 9, the output is 15. How does it work?

I'm someone who writes code just for fun and haven't really delved into it in either an academic or professional setting, so stuff like these bitwise operators really escapes me.  I was reading an article about JavaScript, which apparently supports bitwise operations. I keep seeing this operation mentioned in places, and I've tried reading about to figure out what exactly it is, but I just don't seem to get it at all. So what are they? Clear examples would be great! :D  Just a few more questions - what are some practical applications of bitwise operations? When might you use them?

The following code:  $\dfrac{\left( \dfrac{\left( \dfrac{1}{2}\right) }{2}\right) }{2}$   gives a nasty output:   It seems that the $\left( \right)$ command doesn't do the job.  Any idea how to solve this in general?

Just out of curiousity.. Why are the line endings different for Windows and Unix.  I was looking around for the answer but not found.

Let's say we have 0.33, we need to output 1/3.  If we have 0.4, we need to output 2/5.  The idea is to make it human-readable to make the user understand "x parts out of y" as a better way of understanding data.  I know that percentages is a good substitute but I was wondering if there was a simple way to do this?

i know that|$S_n$|=$n!$ and |$A_n$|= $\frac{n!}{2}$ but i'm not sure where to go from there. Thanks.

i want to make a counter that increases by the value of its inputs, but i did the testbench and the output is undetermined, xxxx. Can someone tell me if there is something wrong in this code?       //Count   module count(clk,    rst, val, coin    ); //Declaración entradas y salidas   input  clk, rst;  input  [3:0] coin;  output [3:0] val;   reg [3:0] val;    reg [3:0] nval;     always @(posedge clk, negedge rst)       if(rst == 0) val &lt;= 4'b0000;       else val &lt;= nval;      always @(val)       nval &lt;= val + coin ;   endmodule

Given a signal wire [7:0] dummy, how can I concatenate it n times?  That is, is there a notation for the following:  {dummy, ..., dummy} // n times   ?

Have you ever tried this before?  static void Main(string[] args) {     int x = 10;     x = x++;     Console.WriteLine(x); }   Output: 10.  but for   static void Main(string[] args) {     int x = 10;     x++;     Console.WriteLine(x); }   Output: 11.  Could anyone explain why this?

So, for example, when I type man ls I see LS(1). But if I type man apachectl I see APACHECTL(8) and if I type man cd I end up with cd(n).  I'm wondering what the significance of the numbers in the parentheses are, if they have any.

I want to print list of numbers from 1 to 100 and I use a for loop like the following:  number=100 for num in {1..$number} do   echo $num done   When I execute the command it only prints {1..100} and not the list of number from 1 to 100.

I have written a Python 3 code, which is:  i = int(input("enter number: ")) print("enter",i)   I'm expecting an output as:  enter number: 5 enter 5   However, I'm getting this:  enter number: 5 ('enter', 5)   What could be the issue? How can I rectify this?

Edit: I was trying to find a general form of the question but I will just put the real question.  My textbook says |a-b|&lt;|b|/2 implies |a|>|b|/2. I don't see how and the text doesn't provide a proof.

As the title says, is there an easy way to output two columns to the console in Java?  I'm aware of \t, but I haven't found a way to space based on a specific column when using printf.

Since $16 \div{-3} = -5.\overline{3}$, I thought I could also express this as $16 \div{-3} = -5\:R\:1$ or in other words $16\mod{-3} = 1$. My calculator tells my it is in fact $-2$.  Along the same lines, I see that $-16\mod{3} = 2$. So, while the true answer evaluates to $-5.\overline{3}$ again, the "remained notation" is $-6\:R\:2$ here, and $-6\:R\:-2$ in the first example.  Why do we go "past" $15$ to $18$ (or in the second example, past $-15$ to $-18$) and calculate the remainder from there?  Further warping my brain, $-16\mod{-3} = -1$, so it looks like we "stop" at $-15$ in this example.

I know how to do it normally, but I could swear that you could fill out out like a[0] = {0,0,0,0}; How do you do it that way? I did try Google, but I didn't get anything helpful.
