Question

我已经生成了一个程序，该程序可以用用户通过键盘给定的限制来计算斐波那契数列，但是我遇到了一个问题，因为我已经要求该数列从1开始，而不是从0开始。我怎样才能做到这一点？我的斐波那契数列显示的是1，而不是0？

X = X.values.reshape(-1, 1)
y = y.values.reshape(-1, 1)
clf.fit(X,y)

Answer 1

使用int previousNumber = 1;，它将从1开始。

Answer 2

只需进行简单的更改并在计算后打印数字即可。

for (int i = 1; i <= maxNumber; ++i)
        {
           // System.out.print(previousNumber+" ");


            int sum = previousNumber + nextNumber;
            previousNumber = nextNumber;
            nextNumber = sum;

            System.out.print(previousNumber+" ");
        }

/*Java Program to find the FibonacciSeries */
public class FibonacciSeries {
   public static void main(String a[]){   
         int limit = 15; /* give limit here */
         int[] feb = new int[limit];
         feb[0] = 0;
         feb[1] = 1;
   /* store all elements in array feb[] */
         for(int i=2; i < limit; i++){
             feb[i] = feb[i-1] + feb[i-2];
         }
    /* print all array elements */
         for(int i=0; i< limit; i++){
                 System.out.print(feb[i] + " ");
         }
    }
}

        public static void main(String[] args) {
        Scanner scanner=new Scanner(System.in);
        System.out.print("Enter the number  of terms: ");
        int count=scanner.nextInt();
        scanner.close();
        
        int firstTerm=1;
        int secondTerm=2;
        int nextTerm;
        
        System.out.println("-----------------------");
        System.out.print("Fibonacci Series: ");
        System.out.print(firstTerm+","+secondTerm);
        
        for(int i=3; i<=count; i++) {
            nextTerm=firstTerm+secondTerm;
            System.out.print(","+nextTerm);
            firstTerm=secondTerm;
            secondTerm=nextTerm;
        }
}
