Reverse digits of an integer.
Example1: x = 123, return 321
Example2: x = -123, return -321
思路：逐步求出x的每一位就行了
代码：
class Solution {
public:
int reverse(int x) {
int y=0;
if(x<0){
x=x*(-1);
while(x!=0){
y=y*10+x%10;
x=x/10;
}
return y*(-1);
}
if(x>=0){
while(x!=0){
y=y*10+x%10;
x=x/10;
}
return y;
}
}
};
