Woocommerce hide out of stock products whole the site. Should hide if its variant is out of stock

I have seen so many links on stakeoverflow that are using some code to hide out of stock product. But its not working for me. I want to hide out of stock products from whole the site.

No matter the product is simple or variable, it should hide the product from whole site. In case of variable product if any of its attribute have 'Out of stock' state then it should hide that product.
