Pbds setup error

I am facing difficulty while setting up pbds. I wrote the same code as is written by Apaar sir but i am having the given 2 errors.
P.S. I have already made the change which is suggested by Apaar sir to change the hash policy file

error: expected nested-name-specifier before ‘__gnu_pbds’
10 | using __gnu_pbds;

error: ‘tree’ does not name a type; did you mean ‘free’?
9 | typedef tree<int, null_type, less, rb_tree_tag, tree_order_statistics_node_update> PBDS;

Since, you’re using windows, you need to change the path variable name.
in the mingw compiler rename,
hash_standard_resize_policy_imp.hpp0000644
and remove the digits after hpp, it should run properly after that.
