Given two integers dividend and divisor, divide two integers without using multiplication, division, and mod operator. The integer division should truncate toward zero, which means losing its fractional part. For example, 8.345 would be truncated to 8, and -2.7335 would be truncated to -2. Retur...
Divide two integers without using multiplication, division and mod operator. If it is overflow, return MAX_INT. ***/#include<stdio.h> #define MAX_INT 2147483647 int divide(int dividend, intdivisor) { if(divisor == 0)return MAX_INT;//除数为零 if(divisor == -1 && dividend == -2147483...
Leetcode c语言-Divide Two Integers Title: Divide two integers without using multiplication, division and mod operator. If it is overflow, return MAX_INT. 这道题就是实现除法,而且不能用到乘法,除法和取余。 第一想法是利用加法,对于一般情况,被除数和除数都是正数,不断累加除数,直到除数大于被除数,这...
