Write a function that returns True if there exists a row that is identical to a column in a 2-D matrix, otherwise False.
To illustrate:
[
[1, 2, 3, 4],
[2, 4, 9, 8],
[5, 9, 7, 7],
[6, 8, 1, 0]
]
# 2nd row + 2nd column are identical: [2, 4, 9, 8]
has_identical([
[4, 4, 4, 4],
[2, 4, 9, 8],
[5, 4, 7, 7],
[6, 4, 1, 0]
]) ➞ True
has_identical([
[4, 4, 9, 4],
[2, 1, 9, 8],
[5, 4, 7, 7],
[6, 4, 1, 0]
]) ➞ False
has_identical([
[4, 4]
[2, 1]
]) ➞ False
has_identical([
[4, 2]
[2, 1]
]) ➞ True
Non-square matrices should return False.
