In this tutorial we will cover Python string operations: concatenation, multiplication, indexing and slicing. So if the numbers are “28” and “25”, then the result will be “700”, To solve this, we will follow these steps −, Taking two arguments x and y it indicates x divides y, if x < −Infinity and y = 1, then return infinity, while a − (left shifted b (left shifted 1 p times)) >= 0, if x > 0 is true and y > 0 is also true, then return ans, otherwise return (− ans), Let us see the following implementation to get better understanding −, Program to add two binary strings, and return also as binary string in C++, MySQL query to multiply values of two rows and add the result. The approach used in below solution is to keep only one array for result. 2144 915 Add to List Share. Simple way of doing this. This article is contributed by Aditya Kumar.
