这道题让我们求两个字符串的相加,之前 LeetCode 出过几道类似的题目,比如二进制数相加,还有链表相加,或是字符串加1,基本思路很类似,都是一位一位相加,然后算和算进位,最后根据进位情况看需不需要补一个高位,难度不大,参见代码如下: classSolution {public:stringaddStrings(stringnum1,stringnum2) {stringres ...
C++ 代码如下: class Solution { public: string addStrings(string num1, string num2) { const int M = num1.size(); const int N = num2.size(); string res; int p1 = M - 1; int p2 = N - 1; int carry = 0; while (p1 >= 0 || p2 >= 0 || carry > 0) { int cur1 = ...
