4. If the sum is equal to the number, print “The number is a perfect number”. 5. If the sum is not equal to the number, print “The number is not a perfect number”. Program/Source Code Here is the source code of the Java Program to Check if a given Number is Perfect Number...
当然,你要是把int范围内的5个Perfect Number(第5个是33550336)都找出来了,直接做判断也行。 publicbooleancheckPerfectNumber3(intnum){int[] primes = {2,3,5,7,13};for(intp: primes) {if((1<< (p -1)) * ((1<< p) -1) == num) {returntrue; } }returnfalse; } 05 小结 算法专题目前...
According to number theory, a limb of pure mathematics that deals with integers, a Perfect Number can be defined as a positive integer whose value is equivalent to the sum of its proper positive divisors, excluding the number itself (alternatively known as aliquot sum). An example of aperfect...
按照你的要求编写的用于判断一个整数n是不是完数的Java程序如下 import java.util.Scanner;public class G { public static void perfectNumber(int n){ int f[]=new int[32]; int sum=0; int j=0; for(int i=1;i<n;i++){ if(n%i==0){ sum=sum+i; f[j]=i; ...
Perfect Number Program in Java Firstly, any number can be a Java Perfect Number if the totality of its positive divisors apart from the number itself is equivalent to that number. For instance: number ‘28’ is a perfect number because ‘28’ is completely divisible by 1, 2, 4, 7, 14...

1. 实现方法 boolean isPerfectNumber(int n) 这个方法用于判断整数n是否为完全数。完全数是指一个数恰好等于它的因子(除了自身以外的因子)之和。 java public boolean isPerfectNumber(int n) { int sum = 0; for (int i = 1; i < n; i++) { if (n % i == 0) { // 检查i是否是n的...

第五章第三十三题(完全数)(Perfect number) **5.33(完全数)如果一个正整数等于除它本身之外其他所有除数之和,就称之为完全数。例如:6是第一个完全数,因为6 = 1 + 2 + 3.下一个完全数是28 = 14 + 7 + 4 + 2 + 1。10000以下的完全数有四个。编写程序,找出这四个完全数。
