 This project is for you to get some practice with parallel programming using ForkJoin. Clone the repo and try each exercise! We recommend going in this order:
 - [LessThan7](src/main/java/LessThan7.java)
-- [Parity](src/main/java/Parity.java)
 - [PowMod](src/main/java/PowMod.java)
+- [Parity](src/main/java/Parity.java)
 - [CountStrs](src/main/java/CountStrs.java)
 - [SecondSmallest](src/main/java/SecondSmallest.java)
