算法day4---将整数的奇数偶数换位

public class demo3 {
    public static void main(String[] args) {
        int a=6;
        System.out.println(a);
        int b=m(a);
        System.out.println(b);
    }
    private static int m(int i){
        int ou=i&0xaaaaaaaa;
        int ji=i&0x55555555;
        return ((ou>>1)^(ji<<1));
    }
