##Twin Primes ###Popular programming languages This chart shows the execution time and CPU usage of the Twin Primes test for multiple popular programming languages based on n = 100,000

Notes that could effect performance:

• All - execution time could be reduced by up to 50% by iterating by two (i.e. 3,5,7 not 3,4,5) (see PHP, C, Swift)
• Java - ArrayList was used to store primes
• Objective-C - NSMutableArray was used to store primes, primes were stored as NSNumber

##Languages which can be compiled by Xcode7 without external compiler Doesn't include C++
