uniq.c Write a program that reads from stdin and filters out duplicate lines of input. It should read lines from stdin, and then print each unique line along with a count of how many times it appeared. Input is case-sensitive, so "hello" and "Hello" are not duplicates. Note that only adjacent duplicates count, so if the input were the lines "hello", "world", and "hello" again, all three would be treated as unique. ./uniq hello hello hello world world # close stdin 3 hello 2 world 3

The output should contain the elements in the same order that they appeared in the original list. (define (filter-lst f lst) 'YOUR-CODE-HERE ) ;;; Tests (define (even? x) (= (modulo x 2) 0)) (filter-lst even? '(0 1 1 2 3 5 8)) ; expect (0 2 8)
