1. Sort the array by values (changing the keys) in ascending, descending order.
2. Also sort the array by values without changing the keys.
3. Filter the odd elements from an array.
4. Sort the different arrays at a glance using single function.
5. Merge the given arrays.
6Find the intersection of two arrays.
7. Find the union of two arrays.
8. Find set difference of two arrays.
