Close #9009

Hi there @hyadav2k!
There seem to be conflicts in the ivy/functional/experimental/elementwise.py. Can you take a recent pull and resolve the merge conflicts? Also there seems to be some failing tests for the PR. Would you mind reviewing this once and try again?

Hi @nathzi1505, thanks for reviewing. The latest commits solves the merge conflicts. The failing tests are not arising due to the changes of this PR, I checked in master as well, and those tests failed.

Meanwhile test_fmin passes all four tests. Below is the o/p for the command pytest test_elementwise.py::test_fmin:
