XOR Swap is a site that is intended to be used by programmers only. Here, they will be able to find all the questions that are asked in interviews by technology-oriented companies such as Google, Electronic Arts, IBM and Facebook among others.
“Given two strings, write a function that determines if all the characters in one string appear at least once in the other” and “When generating random numbers as cookies, how many generations until an expected collision?” are two representative questions that I came across when reviewing the site. More or less, they all follow the same line. And they are all categorized by company, obviously.
Leaving aside its obvious uses, something like XOR Swap is an endless source of inspiration for programmers both young and seasoned. And if they fail to get the exact answers they need by checking the site, they are surely getting an idea or two that could be instrumental in realizing how to solve any problems they are facing themselves.
