两个数字的交替位以创建新数字

给定两个数字，任务是使用两个数字中的替代位来创建结果。我们取第二个数字的第一位，然后取第一个数字的第二位，第二个数字的第三位，取第一个数字的第四位，依此类推，并由此生成一个数字。
例子 ：

Input : n = 10, m = 11
Output : 11
Start from right of second number  
Binary representation of n = 1 0 1 0 
                             ^   ^     
Binary representation of m = 1 0 1 1     
                               ^   ^
Output  is                 = 1 0 1 1        

Input : n = 20, m = 7
Output : 5
Start from right of second number  
binary representation of n = 1 0 1 0 0
                           ^   ^
binary representation of m = 0 0 1 1 1
                         ^   ^   ^
Output  is                 = 0 0 1 0 1   

方法 ：-
1.获得n的设置偶数位数。
2.获得设置的奇数位数m。
3.返回这些数字的OR。
