Given two numbers as stings s1 and s2 your task is to multiply them.
Input: s1 = 33 s2 = 2 Output: 66
Input: s1 = 11 s2 = 23 Output: 253
You are required to complete the function multiplyStrings() which takes two strings s1 and s2 as its only argument and returns their product as strings.
Expected time complexity: O( n1 * n2 )
Expected auxiliary space: O( n1 + n2 ) ; where n1 and n2 are sizes of strings s1 and s2 respectively.
1 <= length of s1 and s2 <= 103
Note:The Input/Ouput format and Example given are used for system's internal purpose, and should be used by a user for Expected Output only. As it is a function problem, hence a user should not read any input from stdin/console. The task is to complete the function specified, and not to write the full code.
