ERLANG LANGUAGE QUESTIONS: 1. Write an Erlang function named sorted that takes one parameter, a list. The function should return true if the list is sorted (from low to high) and should return false if it is not sorted. For example, calling sorted( (1,3,5,5,10] ) should return true, while calling sorted( [2,3,4,5,2] ) should return false. If the parameter is not a list, the function should return error. 2. Write an Erlang function named zip that takes two parameters, both lists. The function should return a single list made by interleaving the contents of both lists. For example, if we called the function zip( [1,2,3,4], [5,6,7,8] ) we should get (1,5,2,6,3,7,4,8). If the lists are not the same length, just add the extra at the end. For example, zip( [1,2,3,4,5], [a,b,c] ) should return [1,a,2,b,3,0,4,5]
