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题目有哪些解题思路? 题目描述 Given two non-negative integers num1 and num2 represented as strings, return the product of num1 and num2, also represented as a string. Example 1: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 Input: num1 = "2", num2 = "3" Output: ...
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 Given two non-negative integers num1 and num2 represented as strings, return the product of num1 and num2, also represented as a string. Example 1: Input: num1 = "2", num2 = "3" Output: "6" Example 2: Input: num1 = "123", num2 = "456" Output: "56088" No...
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.
In the above program, we used an object-oriented approach to create the program. We created an objectSample, and we definedmain()function. Themain()function is the entry point for the program. In themain()function, we created three 2X2 matrices using a two-dimensional array, and then we...
