Difference b/w map and array in CPP. What are generators in Python. What is Polynomial Regression? Normalisation in DBMS.

Question

Accepted Answer

Map and array in CPP are both data structures, but map is a key-value pair container while array is a collection of elements with a fixed size.

Map in CPP is a container that stores elements in key-value pairs, allowing fast lookups based on keys.
Array in CPP is a collection of elements of the same data type, stored in contiguous memory locations.
Generators in Python are functions that allow you to iterate over a sequence of items without storing them all in memory at once.
Polynomial Regression is a form of regression analysis where the relationship between the independent variable and dependent variable is modeled as an nth degree polynomial.
Normalization in DBMS is the process of organizing data in a database to reduce redundancy and improve data integrity.
