Multiply Strings 大数相乘 java 先贴上代码 View Code 思路如下: 模拟竖式相乘 1、转换并反转,字序反转; 2、逐位相乘,结果存放在res[i+j]中; 3、处理进位; 4、转换并反转,将计算结果转换为字符串并反转。 5、消除多余的0; 两数相乘,结果的长度一定不大于乘数和被乘数的长度之和。 上述也可以用直接用java...
multiply-strings(Java) wuxinliulei 做好自己 来自专栏 · 程序员之路 题目描述: 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. public class StringMultipy { public static String getStringMult...
注意JAVA比较字符串相等必须用equals而不能用==;字符转换成int,除了-'0',还需要强制转换(char);char转成String,也要显示转换,使用String.valueOf classSolution {publicString multiply(String num1, String num2) {if(num1.equals("0")|| num2.equals("0"))return"0";int[] product =newint[num1.leng...

43. Multiply Strings 关键词,进位。 public class Solution { public String multiply(String num1, String num2) { int m = num1.length(), n = num2.length(); int[] pos = new int[m + n]; // 0是最高位 for(int i = m - 1; i >= 0; i--) {...
Given two non-negative integers num1 and num2 represented as strings, return the product of num1 and num2, also represented as a string.
Multiply Strings 是一个 Java 题解,用于解决字符串乘法问题。这个问题要求我们实现一个函数,输入两个字符串,输出它们的乘积。 解题思路: 1. 首先,我们需要遍历第一个字符串的每个字符,将其与第二个字符串的每个字符相乘。 2. 然后,我们将结果累加到一个新的字符串中。 3. 最后,返回新字符串作为结果。 代码...
Given two numbers represented as strings, return multiplication of the numbers as a string. Analysis The key to solve this problem is multiplying each digit of the numbers at the corresponding positions and get the sum values at each position. That is how we do multiplication manually. ...
Given two non-negative integers num1 and num2 represented as strings, return the product of num1 and num2.Note:-The length of both num1 and num2 is...
