Can you solve this real interview question? Sum of Two Integers - Given two integers a and b, return the sum of the two integers without using the operators + and -. Example 1: Input: a = 1, b = 2 Output: 3 Example 2: Input: a = 2, b = 3 Output:
LeetCode笔记:371. Sum of Two Integers 问题: 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. 大意: 计算a和b两个整数的和,但是不能用+或-运算符。 比如: 给出 a = 1 和 b = 2,返回...
Sum of Two Integers 题目内容 https://leetcode-cn.com/problems/sum-of-two-integers/submissions/ 不使用运算符 + 和 - ,计算两整数 a 、b 之和。 题目思路 我觉得既然不能使用+-,那么只能进行二进制的运算了。 程序代码......
Sum of Two Integers 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. 不用加减法进行求和运算。 用^来实现二进制的加法,同时用移位来进行进位。 可以用while循环来进行模拟操作,当不用进位的时....
