Leetcode 67:Add Binary(二进制求和) (python.java) Given two binary strings, return their sum (also a binary string). The input strings are both non-empty and contains only characters 1 or 0. 给定两个二进制字符串,返回他们的和(用二进制表示). 输入为非空字符串且只包含数字 1 和 0. Example 1: Input…
Given two binary strings, return their sum (also a binary string). For example, a = "11" b = "1" Return "100". 思路:二进制加法,比較简单.代码例如以下: public class Solution { public String addBinary(String a, String b) { int len = Math.max(a.l…
题目: 二进制中有多少个1 49% 通过 计算在一个 32 位的整数的二进制表式中有多少个 1. 样例 给定 32 (100000),返回 1 给定 5 (101),返回 2 给定 1023 (111111111),返回 9 解题: Java程序: public class Solution { /** * @param num: an integer * @return: an integer, the number of ones in num */ public int countOnes…
Problem Description For non-negative integers x and y, f(x, y) , )=,f(, )=, f(, )=. Now given sets of non-negative integers A and B, for each integer b in B, you should find an integer a in A such that f(a, b) is minimized. If there are more than one…
Given two binary strings, return their sum (also a binary string).The input strings are both non-empty and contains only characters 1 or 0. Example 1: Input: a = "11", b = "1" Output: "100" Example 2: Input: a = "1010&qu…

Given two binary strings, return their sum (also a binary string). For example,a ="11"b ="1"Return"100". 题意:将两个以字符串形式保存的二进制数进行相加. 思路:其实不管是以数组.字符串形式,加或者乘(multiply strings),一般的思路都是从后往前计算,用一个中间变量保存相加或者相乘的结果(加法是一个变量int 或string就行,…
给定两个二进制字符串,返回他们的和(用二进制表示).案例:a = "11"b = "1"返回 "100" .详见:https://leetcode.com/problems/add-binary/description/ Java实现: class Solution { public String addBinary(String a, String b) { String s=""; int c=0; int i=a.len…
