package com.java.learning.recursion;import java.math.*;public class MainClass { public static void main(String args[]){ for(int i = 0; i < 100; i++){ f(i+1); } } public static BigInteger f(long n){ if(n <= 2){ return new BigInteger("1"); }else{ BigInteger n1 = new BigInteger("1"); BigInteger n2 = new BigInteger("1"); BigInteger temp = new BigInteger("0"); for(long i = 0; i < n -2; i++){ temp = n1.add(n2); n1 = n2; n2 = temp; } System.out.println("第" + n + "项为：" + n2); return n2; } }} |
希望本文所述对大家的Java程序设计有所帮助。
