This task needs to be done in Assembly. Convert every lowercase letter in the string `str` to its corresponding uppercase letter. Only ASCII characters should be processed. For this task, the number of executable instructions is limited to n + 300, where n is the length of the string. Use SIMD instructions. Note that the `ptest` instruction was added with SSE4.1 and is not supported by the simulator. Signature: void toupper_simd(char* str); We use x86 intel architecture with SSE and SSE 2 instructions.

Question 7. [11 MARKS] This question has you write the bodies of two functions. Complete each function according to its docstring. Part (a) [6 MARKS] Note: you will most likely not need all of the space on this page. def count_letter_case (L): "" (list of list of str) -> list of tuple of int Precondition: each str in L is non-empty and contains only alphabetic characters Count the number of words in each sublist of L that start with lowercase and uppercase letters. Return a new list where each element is a two-item tuple in which the first item is the number of words in the list at the corresponding index of L that start with a lowercase letter and the second item is the number of words in the list at the corresponding index of L that start with an uppercase letter. >>> count_letter_case([['apple', 'Banana'], ['PEAR'], [], ['PEACH', 'apRICot', 'plum']]) [(1, 1), (0, 1), (0, 0), (2, 1)]

Write a Python program to arrange string characters such that lowercase letters should come first.

Part (b) [3 MARKS] Complete the function body according to its docstring description. You will be marked only on the parts that need to be different from (a). def count_letter_case_mutate (L): " (list of list of str) -> None Type Precondition: each str in L is non-empty and contains only alphabetic characters Replace each item in L with a two-item tuple in which the first item is the number of words in the list at the corresponding index of L that start with a lowercase letter and the second item is the number of words in the list at the corresponding index of L that start with an uppercase letter >>> data = [['apple', 'Banana'], ['PeAr'], [], ['PEACH', 'aprICot', 'plum']] >>> count_letter_case_mutate (data) >>> data [(1, 1), (0, 1), (0, 0), (2, 1)]
