My first idea was that the function abs mentioned the problem with amount, but know my question is, how i...

I'm learning Lua for about a week now and I've built (I hope) a function to print any type in Lua. As I'm new to Lua I don't quite understand: if there is a more succinct way to achieve this if there is a standard way to print nested tables if there are any cases the function doesn't cover fun...

I've written a pretty basic algorithm to convert a string to a binary hash tree of its characters, where each character represents a leaf node. The hash tree itself is being stored in a vector. If the number of leaf nodes is not a power of 2, I'm padding the number leaf nodes with empty substring...

I have the following dataframe: d_test = { 'name' : ['South Beach', 'Dog', 'Bird', 'Ant', 'Big Dog', 'Beach', 'Dear', 'Cat'], 'cluster_number' : [1, 2, 3, 3, 2, 1, 4, 2] } df_test = pd.DataFrame(d_test) I want to identify similar names in name column if those names belong to one cluster ...
