The document provides a Python function named 'do_something' that processes a list and determines its running time equation. It notes that the list's 'pop' operation takes constant time and presents a recursive structure for calculating totals. The key focus is on understanding the performance complexity of the given algorithm.

1. Please write in python. Thank you!
Problem 6 Write down the running time equation, T ( n ) , of the program do_something below.
Note that list's pop takes constant ( ( 1 )) time. def do_something ( L ) : if len ( L ) < 2 : return 1
total = 0 for x in L : total + = x first = L pop ( 0 ) last = L . pop ( 1 ) if first==last: return total +
do_something ( L ) else: return 2 total + do_something ( L )
