Need help with efficientcy of sum

sctong147 — Tue, 04 Oct 2011 20:51:12 +0800

Guys, i have wrote a code to calculate the sum of the lengths whereby
if
syra(1) = 1
syra(2) = n + syra(n/2) if n%2==0
syra(3) = n + (n*3) + 1

eg.
syra(1) will generate 1
syra(2) will generate 2 1
syra(3) will generate 3 10 5 16 8 4 2 1

lengths(3) will be sum of all syra(1),syra(2),syra(3) which is 11.

Here's the code :

public static int lengths(int n) throws IllegalArgumentException{
int syra = n;
int count = 0;
int sum = 0;
if (syra < 1){
throw new IllegalArgumentException("Value must be greater than 0");
}else{
for (int i=1; i<=syra; i++){
count = i;
sum++;
while (count > 1){
if ((count % 2) == 0){
count = count / 2;
sum++;
}else{
count = (count * 3) + 1;
sum++;
}
}
}
}return sum;
}

Question is, if i blast the lengths with big value eg 700000, it will take very long time and do repeat step for those syra(10),syra(5)...which already appear in syra(3). How can I fine tune the code to store some temp (array) of the overlap sequences?

Thanks.

Java L-System

sctong147 — Tue, 27 Sep 2011 00:13:41 +0800

Recently having problem on solving this java asgnmnt and I am lost on this question :

In a Java class called Rewrite write a recursive instance method called lindenmeyer that
takes in a String: start and an integer iters and applies the following set of rules:
A -> AB
B -> BC
C -> D
D -> A
and applies them to the String start simultaneously iter times in succession returning
the new String. By simultaneously we mean that produce a result that looks as if each
rule is applied to input string at the same time. So, for example the call:
lindenmeyer("A",1)
returns the string “AB” and the call:
lindenmeyer("A",2)
returns the string “ABBC” and, finally, the call:
lindenmeyer("A",3)
returns the string “ABBCBCD”.
Hint: parallel rewriting of a string like this is harder than it looks (especially if it is done
in situ) because we have to avoid rules we apply later picking up on changes made by
rules we applied earlier. A simple trick is to make the rules match uppercase letters but
produce lowercase letters. Once all the rewrites are applied you can then convert the
whole string back to upper case.

*any advise would be much appreciated...
