Write a function cumsum() that takes a list l as argument and returns the cumulative sum (also known as the prefix sum) of l, which is a list, say cs of the same length as l such that each element cs[i] is equal to the sum of the first i + 1 elements of l, i. e.,cs[i] == l[0] + l[1] + l[2] + + l[i]you should not modify the argument list l in any way. also, you do not need to assume that l contains numbers; your function should work with any elements that support +. practice goal: although not required, try to solve this without using a nested loop. in this case, you’ll have to write a loop that runs two accumulations in tandem. the first is the standard sum-so-far that we’ve seen several times. the second is an accumulation of the intermediate sum-so-far values into a list (e. g., via an .append() operation); the final value of this list is the desired result.

Show that there is a language a ⚆ {0, 1} â— with the following properties: 1. for all x â a, |x| ≤ 5. 2. no dfa with fewer than 9 states recognizes a. hint: you don’t have to define a explicitly; just show that it has to exist. count the number of languages satisfying (1) and the number of dfas satisfying (2), and argue that there aren’t enough dfas to recognize all those languages. to count the number of languages satisfying (1), think about writing down all the strings of length at most 5, and then to define such a language, you have to make a binary decision for each string about whether to include it in the language or not. how many ways are there to make these choices? to count the number of dfas satisfying (2), consider that a dfa behaves identically even if you rename all the states, so you can assume without loss of generality that any dfa with k states has the state set {q1, q2, . . , qk}. now think about how to count how many ways there are to choose the other four parts of the dfa.
