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...
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...

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...

43. Multiply Strings 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 < 110. Both num1 and num2 contains only digits 0-9.
