Reverse digits of an integer. Example1:x = 123, return 321 Example2:x = -123, return -321 Solution: intreverse(intx){longintisNegative=x<0?-1:1;longintreversed=0;longnum=x*isNegative;while(num){reversed*=10;reversed+=num%10;num/=10;}if((isNegative==-1&&reversed>2147483648)||(...
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=...
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.(给一个整型的数,反转输出) 方法一:数学方法; 1、...
