Problem Description
Given two numbers represented as strings, return the
multiplication of the numbers as a string.
Note:
- The numbers can be arbitrarily large and are non-negative.
- Your answer should not have leading zeroes. For example, 00 is not a valid answer.
DO NOT USE BIG INTEGER LIBRARIES ( WHICH ARE AVAILABLE IN JAVA / PYTHON ). We will retroactively disqualify such submissions and the submissions will incur penalties.1 <= |A|, |B| <= 104
1 <= |A| * |B| <= 106
Input Format
The first argument is a string A, representing the first number.
The second argument is a string B, representing the second number.
Output Format
Return a string, equal to the product of A and B.
Example Input
A = "10"
B = "12"
Example Output
"120"
Example Explanation
A = 10 and B = 12, A * B is 120, return it in the string without leading zeroes.
NOTE: You only need to implement the given function. Do not read input, instead use the arguments to the function. Do not print the output, instead return values as specified.
