Use map() to return the largest element of each pair (tuple) in the list below: pairs = [(7,5),(1,2),(5,2),(9,1),(4,7)]

Sure, here's the code to use map() to return the largest element of each pair (tuple) in the given list:

pairs = [(7,5),(1,2),(5,2),(9,1),(4,7)]
result = list(map(lambda x: max(x), pairs))
print(result)

Output:

[7, 2, 5, 9, 7]

Here, we have used the `max()` function with `lambda` function to find the maximum element in each tuple of the list. Then, we have converted the result into a list using the `list()` function. Finally, we have printed the result.
