Reverse a sentence based on words. The

i

th word from the left in the input sentence is the

i

Multiple correct

16 October 2022

What is the output of the following snippet of code? All words in the list `L` are in lower case. ``` L = ['good', 'done', 'eat', 'trim', 'make', 'fake', 'ease', 'epic', 'cage', 'list', 'tog', 'got'] # L[0][-1] is the last letter of the first word counts = [] count = 1 for i in range(1, len(L)): if L[i - 1][-1] == L[i][0]: count += 1 else: counts.append(count) count = 1 counts.append(count) print(counts) ```

What is the output of the following snippet of code? ``` code = ['# this is a python code', 'x = 0', 'print(x)', 'for i in range(x):', ' x = x + 1', 'print(x)'] mod_code = [] for line in code: if 'print' in line: # there is a single space between the middle quotes line = '#' + ' ' + line mod_code.append(line) for line in mod_code: print(line) ```

`L` is a non-empty list of distinct positive integers. If the following code snippet terminates without any error after a finite number of iterations of the `while` loop, what is the output produced by it? Hint: `L.remove(x)` removes the leftmost occurrence of `x` in `L`. ``` # L is a non-empty list of distinct positive integers # L has already been defined val = 0 for x in L: val += x while L != []: for y in range(1, 11): if y in L: L.remove(y) else: L.append(y) print(val) ```
