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...
LeetCode 371. Sum of Two Integers (两数之和) Calculate the sum of two integersaandb, but you are not allowed to use the operator+and-. Example: Givena= 1 andb= 2, return 3. 题目标签:Bit Manipulation 这道题目让我们做两数之和,当然包括负数,而且不能用+,-等符号。所以明显是让我们从...
其中reference类型实现了和bool的转换,以及operator~来进行反转(0变成1,1变成0)。参数pos是从最低位开始的,比如对bitset<32> i(2);那么i[1]就是1。 bitset可以接收unsigned long long作为构造参数,并且可以用to_ulong()方法返回unsigned long,以及to_ullong()方法返回unsigned long long。 第二步,二进制间加如...
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...Leetcode 371. Sum ...
