【leetcode】43. Multiply Strings 大数乘法 1. 题目 Given two numbers represented as strings, return multiplication of the numbers as a string. Note: The numbers can be arbitrarily large and are non-negative. Converting the input string to integer is NOT allowed....
[LeetCode]43.Multiply Strings 【题目】 Given two numbers represented as strings, return multiplication of the numbers as a string. Note: The numbers can be arbitrarily large and are non-negative. 【分析】 高精度乘法(大数乘法) 其实更多地是考察乘法运算的本质。基本思路是和加法运算有一定的相似处,...
参考LeetCode #415 Add Strings 字符串相加 两个数相乘结果的位数最多不会超过两个数的位数之和 如99 * 99 = 9801 每一次在第 i + j + 1位记录两个数的乘积 然后处理进位 最后将不必要的 0删除即可 时间复杂度O(mn), 空间复杂度O(m + n), 其中 m, n分别为两个字符串的长度 ...
LeetCode Multiply Strings 高精度乘法C++实现 Given two numbers represented as strings, return multiplication of the numbers as a string. Note: The numbers can be arbitrarily large and are non-negative. 这道题就是模拟乘法思维了,还需要模拟加法思维,每一位乘以一个数都要和前面的结果加起来。
