Rand

Using the ‘math/rand’ package of golang to generate a pseudo-random number between [x,n). The bracket at the end means that n is exclusive and x could be any number 0 or greater. The package contains a function Intn which can be utilized to pick a random element in an array or slice of int or string. This example also uses the time package to seed the generator. Otherwise the it would be seeded with a 1 and the generated numbers wouldn’t be random.
