1. C # 代码
(值得注意的是:2^31，超出了int32的限制，所以求最大长度的时候要强制转为int64)public class Solution
{
public int HammingDistance(int x, int y)
{
int maxLen = Convert.ToString((System.Int64)Math.Pow(2,31), 2).Length;
string xbina = Convert.ToString(x,2).PadLeft(maxLen, '0');
string ybina = Convert.ToString(y,2).PadLeft(maxLen, '0');
int count =0;
for(int i=0;i<maxLen;i++)
{
if(xbina[i] != ybina[i])
++count;
}
return count;
}
