Check whether a number is Abundant number or not Wipro previous year coding question

 

Program to check whether a number is Abundant number or not is discussed here. An abundant number is a number for which the sum of its proper divisors is greater than the number itself.

Input & Output format:

• Input consists of 1 integer.
• If it is an Abundant number display Abundant Number or display Not Abundant Number.

Sample input:

12

Sample Output:

Abundant Number

Explanation:

The divisors of 12 are 1, 2, 3, 4 and 6.

The sum of divisors of 12 is 16.

12 < 16.Hence, 12 is an abundant number.

Algorithm to check whether a number is an abundant number or not

• Input a number from the user.
• Find the sum of its divisors.
• If sum < num, print "Abundant Number".
• Else, print "Not Abundant Number".

Program:

n=int(input())

list1=[]
for i in range(1,(n//2)+1):
    if n%i==0:
        list1.append(i)

if sum(list1)>n:
    print("YES")
else:
    print("NO")
