Don't print spaces at the end of a line.
C I/O is faster than C++ I/O.

[helli3papa]

Thank You brainfry
But Where I put space?
and I don't know about string in scanf

Input:

Code: Select all

1
1
8
A

Output should be:

Code: Select all

    A

[techbd123]

Guru! Brianfry! Please help.
Why wa???

[Removed as it was AC then]

[brianfry713]

Line 34: use %d to read an int.
Why is str unsigned?

[techbd123]

Guru! Thanks.

And I made unsigned char for str though it was unnecessary, it could be only char type too.

 AC; THANKS brianfry713 

My problem in this exercise was the input of numbers separated by several blank spaces; as I work with java I Solve the problem with StringTokenizer.

Example:
Input

Code: Select all

2
11
13    2      89         377        8         3 233 34    144    21      1  
OH, LAME SAINT!
15
34   21   13    144 1597 3 987 610 8 5 89        2 377 2584            1
O, DRACONIAN DEVIL!

Before:

Code: Select all

String numeros=br.readLine();
String arreglo[]=numeros.split(" ");

//ERROR

After:

Code: Select all

String numeros=br.readLine();
StringTokenizer tk= new StringTokenizer(numeros);
int cont=0;
while(tk.hasMoreTokens()){
   int arreglo[cont]=tk.nextToken();
   cont++;
}
//GOOD

[brianfry713]

Try input:

Code: Select all

2
11
13    2 89 377 8 3 233 34  144 21 1  
OH, LAME SAINT!
15
34 21 13 144 1597 3 987 610 8 5 89 2 377 2584 1
O, DRACONIAN DEVIL!

Try fixing your code to work on the input I posted, it's the same as the sample input with some extra spaces.
