一.求两个数的最大公约数 如何编程计算N个数的最大公约数(Greatest common divisor)呢?第一想法那便是两两计算,但是往往最简单的想法是不怎么靠谱的.下面用递归来解决.递归有一大好处,那便是递归非常符合人的思维,有时即使很复杂,但是依仗着递归的规律性,可以断定或推测出按递归做是正确的.如果说递归的性能低,我们可以采用备忘录法,用表记录过已经计算过的问题,避免二次计算,这样在一定程度上可以带来性能上的提升.我们可以先用递归实现,倘若在实际情况中发现性能问题,我们可以再进行优化.…
Given an array of integers that is already sorted in ascending order, find two numbers such that they add up to a specific target number. The function twoSum should return indices of the two numbers such that they add up to the target, where index1 m…
题目描述: 不用+,-求两个数的和 原文描述: Calculate the sum of two integers a and b, but you are not allowed to use the operator + and -. Example: Given a = 1 and b = 2, return 3. 方法一:用位运算模拟加法 思路1: 异或又被称其为"模2加法" 设置变量recipe模拟进位数字,模拟加法的实现过程 代码: public class Solutio…
//求两个数中不同的位的个数 #include <stdio.h> int count_different(int a, int b) { int count = 0; int c = a^b; //a,b中不同的位即为1 while (c) { count++; c = c&(c - 1); //把c中最后一个1去掉 } return count; } int main() { printf("%d\n", count_different(3,8)); //3 p…
两个数的最大公约数:不能大于两个数中的最小值,算法口诀:小的给大的,余数给小的,整除返回小的,即最大公约数,(res=max%min)==0? max=min,min=res return min; 两个数的最小公倍数:等于两数之和除以两个数的最大公约数 a*b/(LCM(a,b)); #include <iostream> using namespace std; /*求最大公约数,辗转相除法来求最小公倍数*/ int getLCM(int a, int b) { int max = (a…
