Function receive a two-dimensional square array of random integers.
On the main diagonal, all the negative integers must be changed to 0, while the others must be changed to 1 (Note: 0
is considered non-negative, here).
(You can mutate the input if you want, but it is a better practice to not mutate the input)
Example:
Input array
[
[-1, 4, -5, -9, 3 ],
[ 6, -4, -7, 4, -5 ],
[ 3, 5, 0, -9, -1 ],
[ 1, 5, -7, -8, -9 ],
[-3, 2, 1, -5, 6 ]
]
Output array
[
[ 0, 4, -5, -9, 3 ],
[ 6, 0, -7, 4, -5 ],
[ 3, 5, 1, -9, -1 ],
[ 1, 5, -7, 0, -9 ],
[-3, 2, 1, -5, 1 ]
]
