Problem Description http://oj.leetcode.com/problems/multiply-strings/ Basic idea is to multiply two nums like we do caculation on paper, one by one digital multiplication, then add the temporary results together to get the final one. Be careful about…
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. 题解: 题意就是给你两个字符串型的数字,给这两个数字做乘法. 如果直接转换成Integer做乘法就会溢出. 所以要一步一步来. 下面讲解引用自(http://leetcodeno…
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. 接口: public String multiply(String num1, String num2); 2 思路 大整数的乘法,不能够简单用Integer.valueOf(…

1. Combination Sum Given a set of candidate numbers (C) (without duplicates) and a target number (T), find all unique combinations in C where the candidate numbers sums to T. The same repeated number may be chosen from C unlimited number of times. No…
Multiply Strings 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. 各个位相乘,保存在数组中,最后再处理进位. 如 123*456 4,5,6 8,10,12 12,15,18…
Multiply Strings 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. 题目意思: 给两个string,计算string的乘积. string中的数可以非常大并且是非负数. (就是大数的乘法运算嘛...) 解题思路: 由于之…
