Evil Number in Java | ISC Computer Science 2020 Specimen Paper 2

An Evil number is a positive whole number which has even number of 1s in its binary equivalent.
Example: Binary equivalent of 9 is 1001, which contains even number of 1s. Thus, 9 is an Evil number.
A few evil numbers are 3, 5, 6, 9, …
Design a program to accept a positive whole number ‘N’ where N is greater than 2 and less than 100. Find the binary equivalent of the number and count the number of 1s in it and display whether it is an Evil number or not with an appropriate message.
