...or example count lessThan 7 [5,8,9,1,10] = 2. c. Flatten a list of lists, For example, flatten [[3,5],[],[3,1,1]] = [3,5,3,1,1]. d. Return the count of each item in a list. For example, countItems [2,6,5,5,2,3,5] = [(2,2),(6,1),(5,3),(3,1)]. Note you can return a list of pairs, or return a dictionary (hash or hashmap). e. Rotate a list, by successively removing the last element and adding it to the front. For example rotate 4 [1,2,3,4,5,6]= [3,4,5,6,1,2]. f. Insert a binary operation between each pair of items in a list. For example: insert plus [3,5,7,9] = 3+5+7+9 = 24. 2. Come up with five interesting, and somewhat subtle, programming "mistakes" that are caught by ML's static typing enforcement but allowed to execute under Perl. For each, give an articulate description (us...
