Evil and odious number
If the binary value of a given number 1's count is even, that is an "Evil number". Otherwise it's a "Odious number"
Example-1:
Input : n = 3 Output : Evil number Explain : 3 binary value is "11". The 1's count is even So its "Evil number".
Example-2:
Input : n = 7 Output : Odious number Explain : 7 binary value is "111". The 1's count is odd So its "Odious number".
Solution
public class Main
{
public static void main(String [] args)
{
int n = 3;
String binary = Integer.toBinaryString(n);
int count = 0;
for(int i=0; i<binary.length(); i++)
{
if(binary.charAt(i) == '1'){
count++;
}
}
if(count % 2 == 0){
System.out.print("Evil number");
}
else{
System.out.print("Odious number");
}
}
}
n = 3
s = bin(n)
a = str(s)
b = a.count("1")
if(b % 2 == 0):
print("Evil number")
else:
print("Odious number")
Output
Evil number
