Extra Long Factorials. Discussions. Logic of calculating Factorial is very easy . Big integers must be used for such calculations. We all have done this by hand, but the challenge is to implement this algorithm in code. Find out which one is longer, we always need longer number to be on top and shorter one to be on bottom, so if second is longer than first, we swap two numbers. (see Number. Note: Factorials of can't be stored even in a long long variable. Problem. While JSON is a text format and can represent integers of arbitrary size, you lose precision in JavaScript once numbers are parsed: > parseInt("10765432100123456789") 10765432100123458000 Therefore, if you want to preserve the value of an ID in JavaScript, you need to store it in a string. I used Java 8 to solve the challenge. Once the iteration is complete, we get sum of both digits as our return value. If interested take a look at the requirements. Problem. Extra Long Factorials.
