[Leetcode] 445. Add Two Numbers II 问题:https://leetcode.com/problems/add-two-numbers-ii/#/description 思路:该题与“415. Add Strings”类似,都需要先将原来的数字序列翻转,然后就转化成了跟“2. Add Two Numbers”类似的问题,进而就容易解决多了。 但是本题又规定不允许对原来的链表进行翻转,所以可...
Add Strings: Given two non-negative integers, num1 and num2 represented as string, return the sum of num1 and num2 as a string. Example: Input: num1 = "456", num2 = "77" Output: "533" Solution The basic idea is to add the numbers one by one from tail to head. Code class ...
【Leetcode】Add Strings Given two non-negative integers num1 and num2 represented as string, return the sum of num1 and num2. 1 注意题中num1和num2是以string形式储存的,所以在做运算的时候需要转换成ASCII,用ord()函数 2 题中num1和num2以string形式存储,若不能用build-in函数,则需要先把string...
string addStrings(string num1, string num2) { int i = num1.size() - 1;//获取num1的最后一个字符位置 int j = num2.size() - 1;//获取num2的最后一个字符位置 int add = 0;//进位初始设为0 string ans = "";//用空串来接收结果 ...
classSolution{publicStringaddStrings(String num1,String num2){int i=num1.length()-1,j=num2.length()-1;int carry=0;// 进位StringBuffer sb=newStringBuffer();// 从末尾开始遍历,当存在字符串未遍历完或进位不为0进入循环while(i>-1||j>-1||carry!=0){// 判断是否越界,若越界则用 0 进行...
