Write a Python function to check whether a number is "Perfect" or not. According to Wikipedia : In number theory, a perfect number is a positive integer that is equal to the sum of its proper positive divisors, that is, the sum of its positive divisors excluding the number itself (also known as its aliquot sum).
Sum of all divisors from 1 to n - GeeksforGeeks
WebHere is the easy Java Program to print the summation of all the divisors of an integer number. That means, suppose we have an Integer: 12 as input. The divisors of 12 are, 1,2,3,4,6,12. The sum of all the divisors is: 1+2+3+4+6+12=28. So the output of our program should be like this: 28. Here is the program: Web31 May 2024 · Sum of inverse of divisors is equal to (1/1 + 1/2 + 1/3 + 1/6) = 2.0 Input: N = 9, Sum = 13 Output: 1.44 Recommended: Please try your approach on {IDE} first, before moving on to the solution.
