Define the function print_trophic_class_summary(tli3_values) that accepts a list of trophic level index values and prints a summary outlining the number of lakes in each trophic classification, in order from highest trophic classification to lowest. See the examples for the required format. Notes: Your function must print the summary, not return it. In each state line, the initial number should be formatted with width 3. (Hint: :3 will be helpful) All possible states must be included in the output, even states with zero lakes. The following list will be helpful:     ['Hypertrophic', 'Supertrophic', 'Eutrophic', 'Mesotrophic', 'Oligotrophic', 'Microtrophic', 'Ultra-microtrophic'] You must include and use one of your number_in_trophic_class functions (take your pick!), plus your trophic_class function. Basically, you can start with your answer to Question 5 or 6 and add your print_trophic_class_summary function definition after your previous definitions. For example: Test Result…

Modify following delete() function so that it takes only two arguments, first and x without trail. void delete(listPointer *first, listPointer trail, listPointer x) { if (trail) trail -> link = x -> link; else *first = (*first) -> link; free(x); }
