这个题目和今日 lab 里面的 itoa 比较类似。但是由于 reverse integer 只同样是输出 integer,因此可以把 reversed * 10 后,直接将得到的数字加在reversed后面。 附itoa: char*itoa(intnum,charresult[]){longintnum2=num;if(num==0){result[0]='0';}else{if(num<0){num2=-(longint)num;result[0]='...
Assume we are dealing with an environment which could only store integers within the 32-bit signed integer range: [−231, 231 − 1]. For the purpose of this problem, assume that your function returns 0 when the reversed integer overflows. 题解: 因为还不太会用c++和java,所以用c语言写...
Assume we are dealing with an environment which could only store integers within the 32-bit signed integer range: [−231, 231 − 1]. For the purpose of this problem, assume that your function returns 0 when the reversed integer overflows. 代码: staticvoidMain(string[] args) {intnum =...
The input is assumed to be a 32-bit signed integer. Your function shouldreturn 0 when the reversed integer overflows. Subscribeto see which companies asked this question. 2、代码实现 代码实现1、 通过不了LeetCode 代码解读 public static int reverse(int x) { if (x > Integer.MAX_VALUE || ...
1、C 表示将输入的整数n传给reverse函数 2、C 表示定义一个long型变量res，并初始化 3、B 表示主函数(main)穿进来的值，如果为负数，则取反 4、B 倒置传入的参数number，res*10表示将原来res乘以10，再加上number%10；比喻说你传的是123，而res的初始值是0，123%10=3，那么res...

The bswap instruction reverses the individual bytes of a register and is typically used to swap the endian of an integer to exchange between host and network byte-order(see htons,htonl,ntohs,ntohl). Most x86 compilers implement assembly intrinsics that you can put right into your C or C++ cod...
