Help me re-write pseudo code?

[csisdifficult]

Here it is:


public static StringList power (String s){
StringList answer = new StringList();
// Base case
if (s.length() == 0){
prepend("", answer);
}else{
StringList partial = power(butFirst(s));
String firstChar = first(s);
//pseudocode
StringList prependedP = new StringList();
For each String x in P
insert firstChar + x into prependedP
//end of pseudocode
answer = p + prependedP;
}

return answer;
}

OK

You write the first letter. Then I will write the second letter. Then we take it in turns.

h


damn limits, am i doing it right? :)

@ op: on this forum you will be doing most of the work, we will simply be helping you out.

Original poster, please make a meaningful contribution to this thread before I have to lock it has a homework dump.

I apologize, I thought that was what I was implying. I'm not sure how to go about re-writing the pseudo code, so what steps should I take to begin re-writing it?

[sunde887]

Is the original post pseudo code? It looks closer to real code than pseudo code. Also, please wrap pseudo code, and regular code in code tags.

[/code]

Also, ask specific questions, and say what exactly is giving you trouble.

[Junky]

Sunde if you look close the for each loop near the bottom is the only pseudocode.

[csisdifficult]

Okay, here's the code with code tags:

public static StringList power (String s){
StringList answer = new StringList();
// Base case
if (s.length() == 0){
prepend("", answer);
}else{
StringList partial = power(butFirst(s));
String firstChar = first(s);
//pseudocode
StringList prependedP = new StringList();
For each String x in P
insert firstChar + x into prependedP
//end of pseudocode 
answer = p + prependedP;
}

return answer;
}

No you use a for each loop. If you haven't heard of them do some research.

[sunde887]

Ah, thanks Junky, I'm lazy lol, I only briefly scanned his code.

@op: First you need to understand what a for each loop is. It's basically, for each item x in list of item x.

So I assume you know that arrays must be declared with some type(same with any other collection.) Say you have an array of strings, you can iterate through the loop with a for each loop. I understand a regular for loop does the same thing, but at times a for each loop is nice.

In an array of integers you would do something like this

int[] ints = {1, 2, 3, 4,5, 6, 7, 8};
for(Integer x : ints){
  //do something
}

this loop does something for each item in the loop. Each pass through the loop the current item being worked on can be referenced by x. As a more concreter example, lets multiply each value in the array by 5.

public class By5{
  public static void main(String[] args){
    int[] nums = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};
    for(Integer x : nums){
      x *= 5;
    }
    for(Integer x : nums){
      System.out.println(x);
    }
  }
}

[Junky]

You're lazy? You supplied a for each example whereas I told them to look it up themselves.

[sunde887]

lol, Im lazy when it comes to reading unformatted code.

[csisdifficult]

"For each" loop? I wrote that code with the intention of using just a "while" loop. I've only been taught "while" loops.

[sunde887]

Do you understand how to use a regular for loop?

[csisdifficult]

Yes, but my pseudocode is making it more difficult for me to understand what to write...

What am I initializing, testing, and updating?

So confused...

[sunde887]

Is this your pseudo code, or a professors?
