I'm currently writing a program that helps me recognize functions in numerical sequences that simply writes out the difference between each number.
Like if I give it the sequence [21, 20, 18, 15, 11], it'll return [-1 -2 -3 -4] helping me to recognize that the next number in the sequence is probably 6.
As of now this is my code:
ArrayList<Integer> terms = new ArrayList<Integer>();
Scanner superScanner = new Scanner(System.in);
System.out.println("Enter sequence, separate with comma");
String input = superScanner.nextLine();
String[] splitted = input.split(",");
for(String string : splitted){
int term = Integer.parseInt(string);
terms.add(term);
}
System.out.println("Terms: "+terms);
ArrayList<Integer> sequence = new ArrayList<Integer>();
System.out.println("=========DIFFERENCE=========");
for(int i = 0; i<terms.size(); i++){
//System.out.println("index "+i);
//System.out.println("size "+terms.size());
if(i == terms.size()-1){
//System.out.println("i == terms.size()");
}
else{
int currentTerm = terms.get(i);
int nextTerm = terms.get(i+1);
int difference = nextTerm-currentTerm;
System.out.print(" "+difference);
sequence.add(difference);
}
}
It's pretty simple and straight forward (I'm still learning). However, I was wondering if there's anyway to make it so that the code also returns the "power to".
Like if I give it 16, 256, 65536 it should return the pattern [1, 1]. The two integers would represent the first term power by 1, the second term power by 1, etc. You know, as in 16*16 = 256 etc...
How could I construct a method that do this? Is there any power-to function in java?
Thanks in advance!
