Hi fellows!

This toipic was very helpful to me, thanks!
But how to imitate end of line/newline/line break in the input?

Usually it is ctrl+D, but it doesn't have to work. So you keep typing happily, newlines and all and end it with ctrl+D.

What OP is probably asking is "How do I do this standard I/O thingy?"

Redirection - make an input file (call it , for example, "in"). If your program is "app", then you just do:

Code: Select all

app < in

Or if you want to print output to a file (call it "out"):

Code: Select all

app < in > out

That way you can compare results directly (and if you have diff installed, it is much easier then going through the outputs line-by-line and it catches whitespace difference, too)

I hope that is what he wanted to know :)

Thank you, Darko!

One more question, please.
"Funny Encryption method"- please, explain, how they got hexadecimal representation of 265, and it's binary ?
I think 265==16*16+9, which is A09 in hexadecimal, then we substitute: A=1010, 9=1001, how we got 5 ?

Thank you.

Hi emotional blind!

10019 I believe

In second case you have to consider 265 as hexadecimal number,
as the problem description says (so dont convert dec to hex)

now 2=0010, 6=0110,5=0101
b2=5, OK?

Why did you not post it here,

perhaps i am thinking in a wrong way...for the 2nd part of this problem i am doing it by, converting each digit to the corresponding binary no. and count the no. of 1s, as per as i know this is also another way to convert a decimal no to hex and then binary (

)
i got WA for the code below....

size of rem[10] is too small increase it to 14
the binary of 9999 need greater than 10 digit.

conio.h is a non standard header. NEVER include this header in files to be submitted in UVa.
If you are uncertain about other functions or headers, try checking their portability first.

NEVER open a new thread when there are already many...
