Java Exercises: Find the number of bits required to flip to convert two given integers
Java Basic: Exercise-147 with Solution
Write a Java program to find the number of bits required to flip to convert two given integers.
Example: 27 --> 11011
23--> 10111
Sample Solution:
Java Code:
public class Solution {
public static void main(String[] args) {
System.out.println(bitSwapRequired(27, 23));
}
public static int bitSwapRequired(int x, int y) {
int ctr = 0;
for (int z = x ^ y; z != 0; z = z >>> 1) {
ctr += z & 1;
}
return ctr;
}
}
Sample Output:
2
