Convert an array of Ints to a comma separated string
arrays, closures, swift
Solution
Well you can do it like :
let formattedArray = ([0,1,1,0].map{String($0)}.joined(separator: ",")
Problem
I know that if I want to convert an array of `Int`s to a `String`, I do this: ``` [0,1,1,0].map{"\($0)"}.reduce(""){$0+$1} ``` but I cannot figure out how would I convert an array of `Int`s to a comma separated `String`
