Question

So, I'm trying to get an average revolutions/minute from an input vector.

Here's a sample vector:

V=[10200 11000 11800 12300 13100 13900 14400 15020 15850 16250]

The units are in ms so 10200 is 10.2 seconds.

The revolutions is between every successive value. So 11000 - 10200 is 1 revolutions per 800 ms and et cetera.

I need help figuring out a code that will allow me find the average cadence from the whole dataset.

Thank you in advance

Program :-

import java.util.Scanner;

public class VectorQ {

   public static void main(String[] args) {
       Scanner scan = new Scanner(System.in);
       System.out.print("Enter number of sample vector data : ");
       int data = scan.nextInt();
      
       int i;
       float timeSum = 0f;
       int revolution =0;
       float result;
      
       System.out.println("Enter sample vector data : ");
       int[] v = new int[data];
       for(i=0; i<data; i++)
       {
           v[i] = scan.nextInt();
       }
      
       for(i=1; i<data; i++)
       {
           timeSum += (v[i] - v[i-1]);
           revolution++;
       }
      
       timeSum = (timeSum/1000f);
      
       result = (revolution/timeSum) * 60;
      
      
       System.out.println("average rate = " + (int)result + " revolution/minute");

       scan.close();
   }

}
