LintCode 37. Reverse 3-digit Integer 原创Java参考解答
问题描述
http://www.lintcode.com/en/problem/reverse-3-digit-integer/
Reverse a 3-digit integer.
Example
Reverse 123 you will get 321.
Reverse 900 you will get 9.
解题思路
题目是把原三位数翻转位数。
题目是Reverse Integer翻转整数的naive天真版，只有3位数，不考虑int数字溢出情况。
参考代码
class Solution {
/*
* param number: A 3-digit number.
* return: Reversed number.
*/
public int reverseInteger(int number) {
int result = 0;
while (number > 0) {
result = result * 10 + number % 10;
number /= 10;
}
return result;
}
}
