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...
和sum比较,如果这一次没有继续需要进位的数字了,就可以结束,否则继续下一轮;换一句话就是,答案是把每一轮的sum和carryover拿出来,下一轮继续加一起看一看有没有新的需要进位的地方,所以明显我之前的做法是错的,我只考虑了一轮而已,实际上是每一轮都有可能有新的需要进位的地方。
371. 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. 因为之前完全没有在实际练习中使用过位运算,所以刚看到这道题目的时候我的第一反应是 1.用乘除代替加减,但是一想,觉得...
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....
