Why sum%2 and sum/2 ?
The reason we use sum % 2 and sum / 2 is because we're working with binary numbers, which only consist of 0s and 1s. In binary, each digit can only have a value of 0 or 1, so the base of the number system is 2. Therefore, when adding binary numbers, we need to use sum % 2 to get the value of each binary digit (0 or 1) and sum / 2 to move on to the next digit.
Time complexity : O(n )
Where n is the number of characters in the longer string. This is because, in the worst case, the loop will iterate through each character of the longer string.
Space complexity: O(1)
Where n is the number of characters in the longer string. This is because a StringBuilder object with a length of n is created to store the result of the binary addition.
Coders can test their understanding of programming and actively recall while invoking their memory for more information.
The invocation of memory asking for more information can lead to learning new concepts and reviewing information you may have forgotten.
Flashcards overall solidifies the understanding of a coding problem.
