Problem Explanation

Explanation:

To arrange the table by gender, we can use a sorting algorithm to sort the table based on gender. We can use a custom comparator function to sort the table by gender in ascending order. Once the table is sorted, we can return the sorted table.

Algorithmic Idea:

Define a custom comparator function to compare the gender of two persons.
Use the comparator function to sort the table by gender in ascending order.

Time Complexity:

The time complexity of sorting the table is O(n log n), where n is the number of persons in the table.

Space Complexity:

The space complexity is O(1) as we are not using any extra space apart from the input table.

        Arrays.sort(table, (a, b) -> a[1] - b[1]);
        return table;
    }
